Acute bleeding after bone marrow transplantation (BMT)- incidence and effect on survival. A quantitative analysis in 1,402 patients

Acute bleeding after bone marrow transplantation (BMT) was investigated in 1,402 patients receiving transplants at Johns Hopkins Hospital between January 1, 1986 and June 30, 1995. Bleeding categorization was based on daily scores of intensity used by the blood transfusion service. Moderate and severe episodes were analyzed for bleeding sites. Analysis of the cause of death and the interval of the bleeding episode to outcome endpoints was recorded. Survival estimates were computed for 1,353 BMT patients. The overall incidence was 34%. Minor bleeding was seen in 10.6%, moderate bleeding was seen in 11.3%, and severe bleeding was seen in 12% of all patients. Fourteen percent of patients had moderate or severe gastrointestinal hemorrhage, 6.4% had moderate or severe hemorrhagic cystitis, 2.8% had pulmonary hemorrhage, and 2% had intracranial hemorrhage. Sixty-one percent had 1 bleeding site and 34.4% had more than 1 site. Moderate and severe bleeding was more prevalent in allogeneic (31%) and unrelated patients (62.5%) compared with autologous patients (18.5%). Significant distribution of incidence was found among the different diagnoses, but not by disease status in acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, Hodgkin's disease, and non-Hodgkin's lymphoma. Bleeding was associated with significantly reduced survival in allogeneic, autologous, and unrelated BMT and in each disease category except multiple myeloma. Survival was correlated with the bleeding intensity, bleeding site, and the number of sites. Although close temporal association was evident to mortality, bleeding was recorded as the cause of death in only the minority of cases compared with other toxicities after BMT (graft-versus-host disease, infections, and preparative regimen toxicity). Acute bleeding is a common complication after BMT that is profoundly associated with morbidity and mortality. Although bleeding was not a direct cause of death in the majority of cases, it has a potential prognostic implication as a predictor of poor outcome in clinical assessment of patients after BMT.     

Curative potential of combined modality therapy for advanced Hodgkin's disease

During the period from 1969 through 1977, 124 patients with advanced Hodgkin's disease underwent treatment with combination chemotherapy and radiotherapy. Sixty-three cases were previously untreated, and 61 were relapses following radical radiotherapy for localized Hodgkin's disease. No patient in this series had received prior chemotherapy. Of 102 patients (84%) who have entered complete remission, 92 remain in complete remission with a median follow up time of five years, 10 patients having relapsed, and acute leukemia having developed in 2. The cumulative survival rate for all 124 patients is 80% at five years; the relapse-free survival rate is 74%. In many, if not most cases, the Hodgkin's disease appears to be cured. We have also identified two subgroups of patients for whom the prognosis is worse than for patients with advanced-stage disease as a whole. Patients over the age of 40 years have a five-year survival rate of only 45%, compared with 89% for all other patients. Those Stage IV patients with multiple extranodal sites of involvement have a five-year survival rate of 48%, compared with 81% for other Stage IV patients with only a single extranodal site involved.     

Increased mortality after successful treatment for Hodgkin's disease

PURPOSE: To determine the impact of treatment toxicity on long-term survival in pediatric Hodgkin's disease. PATIENTS AND METHODS: We studied late events in 387 patients treated for pediatric Hodgkin's disease on four consecutive clinical trials at St Jude Children's Research Hospital from 1968 to 1990. Relative risks, actuarial risks, and absolute excess risks for cause-specific deaths were calculated. RESULTS: As of April 1997, 316 (82%) of patients were alive, with a median follow-up of 15.1 (range, 2.9 to 28.6) years. In this cohort, which represented 5,623 person-years of follow-up, 71 fatal events resulted from Hodgkin's disease (n=36), second malignancies (n=14), infections (n=7), accidents (n=7), cardiac disease (n=6), and asphyxiation (n=1). The 5-year estimated event-free survival (EFS) for the entire cohort was 79.6%+/-2.1 %, which declined to 63.1%+/-4.4% by 20 years. Cumulative incidences of cause-specific deaths at 25 years were 9.8%+/-1.6% for Hodgkin's disease, 8.1%+/-2.6% for second malignancy, 4.0%+/-1.8% for cardiac disease, 3.9%+/-1.5% for infection, and 2.1%+/-0.8% for accidents. Standardized incidence ratios showed excess risk for all second malignancies (12; 95% confidence interval [CI], 8 to 17), acute myeloid leukemia (81; 95% CI, 16 to 237), solid tumors (11; 95% CI, 7 to 16), and breast cancer (33; 95% CI, 12 to 72). Standardized mortality ratios also showed excess mortality from cardiac disease (22; 95% CI, 8 to 48) and infection (18; 95% CI, 7 to 38). CONCLUSION: Compared with age- and sex-matched control populations, survivors of pediatric Hodgkin's disease who were treated before 1990 face an increased risk of early mortality related to second cancers, cardiac disease, and infection.     

Outcome of large-bowel perforation in patients with colorectal cancer

PURPOSE: Perforation of the colon is seldom associated with malignant disease. Operative mortality varies widely in published studies and little is known about patterns of failure and long-term outcome. An observational study was undertaken to assess the outcome of colorectal cancer complicated by perforation. METHOD: We reviewed a series of 83 consecutive patients treated during a 14-year period at one institution. RESULTS: Fifty-four (65 percent) patients had perforation of the tumor itself, and 29 (35 percent) had diastatic perforation proximal to an obstructing tumor. Twenty-six (31.5 percent) patients had metastatic disease at laparotomy. Primary resection of the diseased segment was performed in 47 (87 percent) patients with perforation of the tumor itself and in 21 (72.4 percent) patients with diastatic perforation proximal to an obstructing tumor. However, only 57 patients (39 (72.2 percent) with perforation of the tumor itself; 18 (62 percent) with diastatic perforation proximal to an obstructing tumor; P = not significant) were potentially cured. Operative mortality was 16.7 and 48.3 percent, respectively (P < 0.01) and correlated significantly with Hinchey's stage (P < 0.001) and advanced disease (P = 0.023). At a mean follow-up of 43 (median 31) months, 21 (46 percent) of the 46 potentially cured survivors were alive. The local recurrence rate was 22.9 percent in patients with perforation of the tumor itself and 18.2 percent in patients with diastatic perforation proximal to an obstructing tumor (P = not significant). Peritoneal seeding occurred in 17 and 0 percent (P = not significant); the mean disease-free interval was 33.9 and 49.9 months (P = not significant); and five-year cumulative disease-related survival probability was 0.51 and 0.90 (P = 0.049), respectively. CONCLUSIONS: Diastatic perforation proximal to an obstructing tumor is associated with higher operative mortality and better cancer-related survival than a tumor perforating through the bowel wall. Early diagnosis in diastatic perforation and aggressive management of sepsis associated with radical surgical resection is recommended.     

Control of cardiac output in essential hypertension

We reviewed 179 patients who had undergone thoracotomy and resection of a suspected malignant coin lesion of the lung over the past 20 years to see if a policy of early thoracotomy was therapeutically valid. The average diameter of all lesions was 1.6 cm; the average diameter of 27 malignant lesions (15 percent) was 1.8 cm. Follow-up of the 27 patients with malignant neoplasms was 100 percent. The present survival rate of the 19 patients with primary lung cancer is 89 percent (17/19). Of 12 cases of primary lung cancer followed for five years, ten (83 percent) survived. The five-year survival of the eight patients with metastatic lesions was 25 percent (2/8). There were no postoperative deaths and few serious postoperative complications (four patients or 2 percent). Very small primary lung cancers detected and treated early do have the same poor prognosis as larger primary cancers.     

Allergic granulomatous angiitis in a patient with positive reactions on serological tests for parasite antigens

PURPOSE: Colorectal cancer screening has become prevalent. To discuss the efficacy of screening, we studied the characteristic of asymptomatic colorectal cancer detected by screening. METHODS: This is a retrospective review of patients with colorectal cancer treated at our institution. During the past 20 years, 96 of 1,046 cases of colorectal cancer were asymptomatic and detected by screening. Sixty-one of these cases were detected in the recent five years. The initial screening procedures were fecal occult blood test in 51 cases, sigmoidoscopy or colonoscopy in 18, barium enema in 9, and other tests in 18. RESULTS: Thirteen lesions (14 percent) were smaller than 1.0 cm and 32 (33 percent) were 1-2 cm in size. There were 34 Tis, 21 T1, and 8 T2 tumors. Of the 55 Tis or T1 lesions, 14 showed nonpolypoid growth (5 flat-elevated, 7 flat-elevated with depression, 1 flat, 1 depressed), and 12 of these were detected on endoscopy. Thirty-four cases were TNM Stage 0, 25 were Stage I, 16 were Stage II, 12 were Stage III, and 9 were Stage IV. Sixty-one percent of those detected by screening were in either Stage 0 or Stage I compared with 16 percent in the symptomatic group. Cumulative five-year disease-free survival rates were 100 percent for both Stage 0 and Stage I, 94 percent for Stage II, and 52 percent for Stage III. Overall cumulative five-year survival rate was 87 percent for those detected by screening, compared with 57 percent in symptomatic patients. CONCLUSIONS: Asymptomatic cancers detected by screening were at a less advanced stage. In particular, many nonpolypoid early cancers were detected by endoscopic screening.     

Randomized, double-blind, placebo-controlled study of the preventive effect of supplemental oral vitamin C on attenuation of development of nitrate tolerance

Although resection for pancreatic cancer is occasionally curative, its major value lies in restoring patients to a more normal life. The objective of this study was to evaluate the functional quality of life (QoL) of patients undergoing various treatments for pancreatic cancer using a nationwide, multi-institutional, non-referral patient population. From 822 pancreatic cancer patients treated from 1989 to 1995, and listed in the Department of Defense (DoD) hospital central computerized tumor registry, we selected 781 with evaluable survival information. Local tumor registrars had contacted patients at least yearly and prospectively compiled a QoL index using a self-reported Karnofsky performance status (KPS); values were obtained for patients alive in March of 1995 and/or 1996. Survival duration and KPS scores were then compared by stage and treatment using analysis of variance (F-test). Resection significantly increased KPS and mean survival time with stage I-II cancers and improved mean survival time, but not KPS, in patients with node positive (stage III) disease. The projected five-year survival rate after resection in stages I-II was 24% but zero for stage III. Patients receiving combined chemo- and radiation therapies, whether given as adjuvant or primary treatment, had significantly longer mean survival duration. However, KPS scores were not higher in treated patients. These data indicate that patients live longer and better lives after resection of localized pancreatic cancers, but QoL measurements do not support resection for pancreatic cancer involving lymph nodes. Unresected patients selected for combined chemo- and radiation therapy live longer, but not better, lives.     

Modest decline in late mortality following Hodgkin's disease in the southeastern Netherlands since 1972

Since prolonged remission can be induced in the majority of patients with Hodgkin's disease (HD), treatment-related mortality and morbidity have emerged. We investigated whether awareness of toxicity diminished treatment-related mortality for unselected patients treated between 1972 and 1993 in general hospitals in the southeastern Netherlands. We also estimated the prevalence of treatment-related morbidity among patients treated in the 1980s. Data were collected on all 345 HD patients registered in the Eindhoven Cancer Registry between 1972 and 1993. Medical records and histology were reviewed; follow-up ended in 1994. Administration of MOPP chemotherapy decreased, and there was a shift from total nodal irradiation to less extended low-dose radiotherapy. For cured patients the 10-year relative survival improved from 84% in the 1970s to 90% in the 1980s, which is reflected by a decline in excess mortality from 16% to 10%. The 10-year relative mortality risk due to secondary malignancies decreased from 4.3 (95% CI, 1.2-7.4) to 3.0 (CI 0.2-5.8), which is also reflected by a decline in the 10-year cumulative incidence for all cancers from 10% to 5%. However, the relative risk of late cardiovascular death, which is closely related to previous irradiation, barely changed, as shown by a decrease from 2.4 (CI 0.4-4.5) to 2.2 (CI.0-4.7). HD survivors profited less from the sharp decline in cardiovascular mortality observed for the general population. Among patients, the prevalence of serious treatment-related morbidity 5 years or more after initial diagnosis was 34%. In conclusion, modest decline in excess mortality among cured HD patients was observed in the 1980s, as reflected by a decrease in mortality due to second malignancies. However, late mortality, especially due to radiation-related cardiovascular disease, is still substantial. About one third of HD survivors suffer radiation-induced sequelae. Clinical trials to find ways to minimize iatrogenic complications are important.     

Radiolabelled antimicrobial peptides for imaging of infections: a review

Risk factors suggestive of relatively late exposure to EBV have been consistently associated with Hodgkin's disease (HD) in younger adults. In addition, evidence of EBV infection has been found in the Reed-Sternberg cells themselves in about one-third to one-half of all HD cases. However, no study yet published has correlated these childhood social environment risk factors with the presence of EBV in Hodgkin's tumor cells. We examined whether EBV-positive HD occurs in those patients whose childhood environment would predispose them to relatively late exposure to EBV. The study population consisted of 102 cases of mixed cellularity (MC; n = 25) or nodular sclerosing (n = 77) HD. Samples that tested positive for either EBV-encoded RNA or latent membrane protein or both were considered EBV-positive. Of the 102 cases, 83 completed a questionnaire regarding childhood social environment. The association with EBV-positivity was estimated by the odds ratio (OR) with 95% confidence intervals (CI). Twenty-two percent of the cases were EBV-positive. These cases were more likely to be MC (OR, 6.2; CI, 2.3-16.3) and male (OR, 3.4; CI, 1.3-9.0). History of infectious mononucleosis (IM) was not predictive of EBV-positivity, with only 3 of 14 such patients being EBV-positive (P = 0.82). Contrary to our hypothesis, no association between EBV and childhood environment risk factors was identified. The association of EBV with MC histology and male gender agrees with previous reports. The most intriguing finding was the dissociation between IM history and EBV-positivity, in that almost all of the cases with a history of IM were EBV-negative.     

Bone marrow transplants from unrelated donors for patients with chronic myeloid leukemia

BACKGROUND: Chronic myeloid leukemia can be cured by marrow transplantation from an HLA-identical sibling donor. The use of transplants from unrelated donors is an option for the 70 percent of patients without an HLA-identical sibling, but the morbidity and mortality associated with such transplants have been cause for concern. We analyzed the safety and efficacy of transplants from unrelated donors for the treatment of chronic myeloid leukemia and identified variables that predict a favorable outcome. METHODS: Between May 1985 and December 1994, 196 patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase received marrow transplants from unrelated donors. RESULTS: The median follow-up was 5 years (range, 1.2 to 10.1). Graft failure occurred in 5 percent of patients who could be evaluated. Acute graft-versus-host disease of grade III or IV severity was observed in 35 percent of patients who received HLA-matched transplants, and the estimated cumulative incidence of relapse at five years was 10 percent. The Kaplan-Meier estimate of survival at five years was 57 percent. Survival was adversely affected by an interval from diagnosis to transplantation of one year or more, an HLA-DRB1 mismatch, a high body-weight index, and an age of more than 50 years. Survival was improved by the prophylactic use of fluconazole and ganciclovir. The Kaplan-Meier estimate of survival at five years was 74 percent (95 percent confidence interval, 62 to 86 percent) for patients who were 50 years of age or younger who received a transplant from an HLA-matched donor within one year after diagnosis. CONCLUSIONS: Transplantation of marrow from an HLA-matched, unrelated donor is safe and effective therapy for selected patients with chronic myeloid leukemia.     

Survival and complications of radiotherapy following involved and extended field therapy of Hodgkin's disease, stages I and II. A collaborative study

A collaborative trial with random assignment to involved field or extended field radiotherapy for localized Hodgkin's disease was begun in 1967. Case accession was completed in 1973, with 224 eligible patients assigned to involved field and 243 to extended field. With a median follow-up time of 27 months no significant survival difference is found between involved and extended field regimens for the total patient group or for most subgroups defined by age, sex, histology, stage, class, and use of laparotomy for staging. A single exception is an improved survival in the involved field group for female patients. Survival free of distant extension shows a similar lack of treatment effect, but survival free of any extension, local or distant, shows a significant benefit from extended field treatment. Complications of radiotherapy are significantly increased following extended field treatment. Survival following local extension is similar to survival following periods free of any extension.     

The value of gallium imaging after therapy for Hodgkin's disease

BACKGROUND: Although it is used widely, the value of gallium imaging in managing Hodgkin's disease remains unclear. METHODS: A retrospective review of gallium imaging and treatment outcome in 60 patients with Hodgkin's disease treated between January 1990 and July 1995 was conducted. The minimum follow-up was 1 year. RESULTS: Based on gallium imaging, 46 patients were in complete remission (CR) after initial treatment, 10 were in partial remission (PR), and 4 had persistent or progressive disease (NR). Ten of 29 patients (34%) with gallium CR after chemotherapy subsequently recurred, compared with no recurrences in 17 patients receiving initial radiotherapy or combined chemoradiation. Eight of ten patients received further therapy after gallium PR, and nine patients remained disease free at last follow-up. Survival did not differ in patients achieving a gallium CR or PR. CONCLUSIONS: Gallium-67 imaging may help confirm the presence of active Hodgkin's disease, but was unreliable in defining disease remission after chemotherapy in this study population. Patients with a gallium PR may still have a good prognosis after additional therapy.     

Body mass index and mortality in a general population sample of men and women. The Buffalo Health Study

The objective of this research was to investigate the long-term relation between body mass index (BMI) and mortality from all causes and from specific causes in the general population. A 29-year follow-up study was conducted in a random sample of white men (n = 611) and women (n = 697) aged 20-96 years who were residents of Buffalo, New York, in 1960. At baseline, height and weight were determined by self-report. BMI was calculated as weight (kg)/height (m2). During the follow-up period, 295 (48.3 percent) men and 281 (40.3 percent) women died. With the Cox proportional hazards model and adjustment for age, education, and cigarette smoking, a significant linear association was found between BMI and all-cause mortality in men less than age 65 years at baseline (relative risk (RR) = 1.06, 95 percent confidence interval 1.02-1.09), but not in women (RR = 1.02, 95 percent confidence interval 0.99-1.05). In men age 65 years and older, the relation was quadratic in form (p = 0.02), with the lowest risks appearing in the BMI range of 23-27. BMI was most strongly related to cardiovascular disease (CVD) and coronary heart disease mortality in women and younger men. No such associations were observed in older men. BMI was not related to an increased risk of death from non-CVD or cancer in either sex. These findings illustrate the importance of BMI as a risk factor for CVD and coronary heart disease mortality in certain gender-age groups and indicate that the majority of the impact of BMI on overall mortality is due to the strong relation between relative weight and these specific causes of death.     

Detection of relapse in early-stage Hodgkin's disease: role of routine follow-up studies

PURPOSE: To examine the costs and benefits of routine follow-up evaluation in patients treated with radiation therapy for early-stage Hodgkin's disease. PATIENTS AND METHODS: We retrospectively examined patterns of follow-up evaluation and methods of relapse detection among 709 patients with stage I and II Hodgkin's disease treated with primary radiotherapy between 1969 and 1994. We determined the probability of relapse detection for seven routine follow-up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of survival following salvage therapy. RESULTS: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range, 0 to 13 years) posttreatment. Relapse was suspected primarily by history (Hx) in 55% of patients, physical examination (PE) in 14%, chest x-ray (CXR) in 23%, and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study. The rate of relapse detection was highest for a combination of Hx and PE (78 of 10,000 examinations) followed by CXR (26 of 10,000 examinations). The projected charges (1995 dollars) per relapse detected by routine follow-up Hx and PE were $11,000 compared with $68,000 for CXR and $142,000 for KUB. The 10-year actuarial survival rate following salvage therapy was 65% overall, 65% for patients in whom relapse was detected by Hx or PE, and 69% for patients in whom relapse was detected by radiographs (P = not significant). CONCLUSION: The majority of relapses occurred within 5 years of treatment and were identified by Hx and PE. CXR was useful during the first 3 years of follow-up evaluation. KUB, CBC, and laboratory studies accounted for nearly half of all follow-up charges and rarely led to the detection of relapse. Their routine use as a method of relapse detection is questionable. In general, the method of relapse detection did not have a significant impact on the likelihood of successful salvage therapy.     

Familial dilated cardiomyopathy

The author surveys the literature and gives a state of art of familial dilatative cardiomyopathy including his own experience. In the past two decades, III familial dilatative cardiomyopathy cases have been encountered in 30 families in their own material, which means a 21.5 percent incidence rate as concerns the total number of dilatative cardiomyopathy patients. The inheritance pattern was autosomal dominant in the majority of the cases. Both cardiomegaly (20 vs 29.6 ys) and the complaints (29.9 vs 37.6 ys) displayed an earlier onset in familial dilatative cardiomyopathy than in the nonfamilial form. The characters of the signs and symptoms did not differ otherwise between the two groups. Significant differences were observed between the two groups in the progression of the disease: the five-year survival rate after the onset of the symptoms was 23.1 percent in the familial cases and 52.1 percent in the non-familial form (p = 0.026).     

Results of salvage abdominoperineal resection for anal cancer after radiotherapy

PURPOSE: Nonsurgical treatment of anal cancer by radiotherapy alone or combined with chemotherapy is the standard therapy for epidermoid carcinoma of the anal canal. Surgery is only recommended for treatment failures. Very few studies have been devoted to the outcome of this salvage surgery. The aim of this study is to evaluate these results. METHODS: A retrospective review from 1986 to 1995 revealed 21 patients with residual or recurrent anal canal carcinoma after initial radiotherapy, operated on by abdominoperineal resection. Patients were reviewed as to age, gender, initial treatment, any symptoms of recurrence, duration until recurrence, any diagnosis imaging, treatment, and outcome. RESULTS: None of these 21 patients had known lymph node involvement or metastases at radiotherapy or at salvage abdominoperineal resection. Eleven patients had residual disease (positive biopsy less than 6 months after the end of radiotherapy) and 10 had tumor recurrence (more than 6 months after cessation of treatment). Recurrence occurred at a mean of 15 (range, 9-41) months after radiotherapy. All 21 patients underwent an abdominoperineal resection. Pathologic examination of the 21 specimens showed complete excision in all cases except one and lymph node metastases in two cases. There was no perioperative mortality. The mean follow-up after surgery was 40 months; no patients were lost to follow-up. Of the 21 patients, 10 died and 11 lived, of whom 9 are disease free. The overall survival rate at three years after salvage abdominoperineal resection was 58 percent. The overall survival rate for patients with residual disease (vs. recurrence) at three years was 72 percent (vs. 29 percent) and at five years was 60 percent (vs. 0 percent; P = 0.06). CONCLUSIONS: Salvage abdominoperineal resection for anal cancer can be expected to yield a number of survivors from residual disease, but the low rate of survival after abdominoperineal resection for recurrent disease suggests the need for additional postoperative treatment if salvage abdominoperineal resection is performed.     

Risk of subsequent malignant neoplasms among 1,641 Hodgkin's disease patients diagnosed in childhood and adolescence: a population-based cohort study in the five Nordic countries. Association of the Nordic Cancer Registries and the Nordic Society of Pediatric Hematology and Oncology

PURPOSE: To assess the risk of subsequent malignant neoplasms among Hodgkin's disease patients diagnosed before 20 years of age in the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden). PATIENTS AND METHODS: There were 1,641 Hodgkin's disease patients identified through the national cancer registries since the 1940s or 1950s. The patients were monitored for 17,000 person-years until the end of 1991. Expected figures were derived from the age-specific incidence rates in each country and standardized incidence ratios (SIR) were calculated. RESULTS: A total of 62 subsequent neoplasms were diagnosed (SIR, 7.7; 95% confidence interval [CI], 5.9 to 9.9). The overall cumulative risk of subsequent neoplasms was 1.9% at the 10-year follow-up point, 6.9% at 20 years, and 18% at 30 years. There were 26 subsequent neoplasms among males (SIR, 6.5; 95% CI, 4.3 to 9.6) and 36 among females (SIR, 8.9; 95% CI, 6.2 to 12), of which 16 were breast cancers (SIR, 17; 95% CI, 9.9 to 28). High risks were seen for thyroid cancer (SIR, 33; 95% CI, 15 to 62), for secondary leukemia (SIR, 17; 95% CI, 6.9 to 35), and for non-Hodgkin's lymphoma (SIR, 15; 95% CI, 4.9 to 35). The relative risk increased from 3.3 (95% CI, 1.2 to 7.1) for Hodgkin's disease patients diagnosed in the 1940s and 1950s to 15 (95% CI, 7.4 to 27) in the 1980s. The highest risk of secondary leukemia (SIR, 68; 95% CI, 18 to 174) was seen among those diagnosed with Hodgkin's disease in the 1980s. CONCLUSION: Patients who survive Hodgkin's disease at a young age are at very high relative risk of subsequent malignant neoplasms throughout their lives. In particular, the high relative risk of breast cancer following Hodgkin's disease in the teenage years calls for enhanced activity for early diagnosis.     

Cancer incidence, mortality and survival: trends in four leading sites

Cancer mortality rates in the United States have stabilized in the past few years after rising for more than 50 years. Incidence and mortality rates for all cancers tend to be higher among men than women, among blacks than whites and among those over age 65. In 1994 cancer of the lung, prostate, breast, and colon/rectum (colorectal) will account for an estimated 57 percent of all new cancer cases and 55 percent of cancer deaths. Analysis of incidence, mortality and survival rates of these four major cancers indicate some encouraging trends. That is, even though age-adjusted incidence rates continue to increase, it appears that educational and screening efforts are having a positive influence on mortality rates. Lung cancer incidence has declined in recent years following a decrease in smoking among men that began some 20 years ago; evidence also indicates a start of a declining trend in their mortality from this disease, as well. Lung cancer incidence and mortality rates among women, however, continue to rise. In 1986 lung cancer became the leading cause of cancer deaths among women. Increased use and improved techniques of cancer detection for prostate, breast and colorectal cancers are resulting in larger numbers of these cancers being detected at early stages when they are more readily treatable. It is hoped that such activities will ultimately reduce mortality for these three major cancer sites.     

Oesophageal cancer associated with other primary cancers: a study of 31 patients

The aim of this study was to investigate the characteristics of oesophageal cancer associated with other primary cancers and the survival rate after surgery for the patients with these cancers. Of 202 patients with oesophageal cancer treated in the Second Department of Surgery, Shinshu University School of Medicine between 1981 and 1995, 31 patients (15.3%) had oesophageal cancer associated with other primary cancers. Twenty-one synchronous and 10 metachronous associated cancers were found and 25 of them were resected. Early-stage oesophageal cancer was much more frequent in the associated cases than in the non-associated cases. The stomach was the most frequently associated organ. The numbers of cases with triple and quadruple cancers were three and one, respectively. Three of these cases had intervals of over 6 years between tumours. Three cases with other primary cancers which had intervals of over 7 years after oesophagectomy were found, and two were carcinomas of the reconstructed gastric tube. In the outcome after surgery for oesophageal cancer, there was no difference between the associated and the non-associated cases, and also no difference between the synchronous and metachronous associated cases. Regarding the five-year and 10-year survival rates after surgery for the first cancers, the synchronous cases had a poorer outcome than did the metachronous cases. In conclusion, oesophageal cancer with other primary cancers is not always rare, and its outcome is not poor compared with that of the non-associated cases. These patients may achieve survival by early detection of both lesions and positive treatment. It is important to consider the risk of other primary cancers after oesophagectomy, and the success of the reconstructed gastric tube should be followed by endoscopy.     

Photodynamic therapy (PDT) and photodiagnosis (PD) using endogenous photosensitization induced by 5-aminolevulinic acid (ALA): current clinical and development status

Although low levels of social support have been related to mortality from coronary heart disease, little is known about the role of social support among Mexican Americans. The authors therefore examined the relationship between social support and long-term survival in the Corpus Christi Heart Project. They developed a social support scale that used data collected during in-hospital interviews of 292 Mexican Americans and 304 non-Hispanic Whites who survived a myocardial infarction for more than 28 days. The scale incorporated three measures: marital status; if not married, whether living alone; and whether advised to seek help. During an average follow-up period of 43 months, 115 participants died. Survival following myocardial infarction was greater for those with high or medium social support than for those with low social support. With age, gender, ethnicity, education, employment, smoking, diabetes, hypertension, and hypercholesterolemia included in a proportional hazards regression model, the relative risk of mortality was 1.89 (95% CI, 1.20-2.97) for those with low social support. But when the two ethnic groups were analyzed separately, low social support was no longer a significant predictor of mortality for non-Hispanic Whites, whereas for Mexican Americans, the relative risk of mortality was 3.38 (95% CI, 1.73-6.62) for those with low social support.
