Breast cancer in older women

The American Geriatric Society currently recommends screening mammography for women up to 85 years of age whose life expectancy is three years or longer. The value of clinical breast examinations in older women needs further study. Total mastectomy and partial mastectomy with postoperative radiation therapy yield similar results in localized breast cancer. Postoperative irradiation may be avoided in women with small tumors (2.5 cm or less in diameter) who have undergone quadrantectomy. Lymph node dissection is important for tumor staging but significantly increases the risks and morbidity of surgery. Lymph node mapping may obviate the need for lymphadenectomy in many older women. Adjuvant hormonal therapy for at least two years appears to be beneficial in all women with hormone-receptor-rich tumors. Adjuvant chemotherapy is indicated in women with lymph node involvement or high-risk tumors with no lymph node involvement. Unless life-threatening metastases are present, hormonal therapy is the first approach to metastatic cancer. Chemotherapy is indicated if endocrine therapy is unsuccessful or life-threatening metastases are present. Most chemotherapy regimens appear to be well tolerated, even by women over 70 years of age. Special treatment should be employed for metastases to tumor sanctuaries (i.e., brain, eyes), the long bones, the spine and the chest wall.     

Breast cancer in older women

Successful laser treatment of haemangiomas requires selective photocoagulation of subsurface targeted blood vessels without thermal damage to the overlying epidermis. We present an in vivo experimental procedure, using a chicken comb animal model, and an infrared feedback system to deliver repetitive cryogen spurts (of the order of milliseconds) during continuous Nd:YAG laser irradiation. Gross and histologic observations show deep-tissue photocoagulation is achieved, while superficial structures are protected from thermal injury due to cryogen spray cooling. Experimental observation of epidermis protection in chicken comb animal models suggests selective photocoagulation of subsurface targeted blood vessels for successful treatment of haemangiomas can be achieved by repetitive applications of a cryogen spurt during continuous Nd:YAG laser irradiation.     

Breast cancer in pregnant and lactating women

Between 1988 and 1991, we treated 595 women with breast cancer in the Breast Disease Section of the Cancer Research Foundation of Pakistan. We report here on 61 patients who were pregnant or lactating. Most patients presented at a late stage of disease because of ignorance, social taboos, or fear of hospitalization and operation. The largest diameter of the breast mass at presentation was 15 cm. Lymph nodes were involved in 70.5% of cases. Multiparity, young marriages, malnutrition, and unhygienic conditions are ripe in the rural environment of Pakistan. No oral contraceptives are used. Modern and conventional methods of treatment did not increase the survival rate of these cancer patients.     

Breast cancer screening and related attitudes among Filipino-American women

This study assessed mammography screening rates and related attitudes and intervention preferences in Filipino-American women, a group that has been neglected in cancer control research. Face-to-face interviews were conducted in English and Tagalog with a convenience sample of 218 Filipino women 50 years and older residing in Los Angeles. Sixty-six % had ever had a screening mammogram, 42% had had one in the past 12 months, and 54% in the past 2 years. These rates are about 20% lower than those found among African-American and white women in the 1994 California Behavioral Risk Factor Survey. Women who had received a doctor's recommendation to obtain a mammogram, women stating that they were very likely to obtain a mammogram if a physician recommended it, and women who felt very comfortable requesting a mammogram from a physician were more likely to have been screened. Women who had friends and relatives who had obtained mammograms those stating that their friends and relatives would be very supportive of their getting a mammogram, and those who felt that it was very worthwhile to obtain a mammogram were also more likely to have been screened. The following variables were negatively related to the outcome: concern over cost, the attitude that mammograms are only needed in the presence of symptoms, perceived inconvenience of taking the time and difficulties getting to the mammography facility, and embarrassment. Implications for interventions to increase breast cancer screening are discussed.     

Breast cancer detection by daughters of women with breast cancer

The preferred therapy for genuine stress incontinence is surgery. The Burch procedure is considered by many to be the gold standard for surgical treatment of genuine stress incontinence. The Burch procedure requires the elevation of the anterior wall of the vagina to the level of the origin of the paravaginal fascia by suspension from Cooper's ligaments. The laparoscopic performance of the Burch procedure by suturing or by endoscopic stapler mesh technique results in a decrease in the length of hospital stay, faster recovery, much shorter catheterization and less scarring due to the smaller incisions. The laparoscopic procedure provides results similar to the open operation if a meticulous technique is used. Long-term follow-up will be necessary before these procedures can be generally offered as a therapeutic alternative.     

Maximal cytoreductive surgery in advanced ovarian cancer

The standard form of surgical intervention in advanced ovarian cancer is to undertake a pelvic clearance, and remove all tumour. When the latter is not feasible, then a ‘debulking’ operation is performed. This is a procedure whereby the intra-abdominal tumour load is reduced to what is termed ‘optimum’ residual disease (which has varied definitions). Compared with other intra-abdominal solid tumours, this approach is unique to ovarian malignancies. Whilst many retrospective studies, and meta-analyses may indicate that patients with ‘optimum’ debulking survive longer than those with a greater amount of residual disease, the reality is that this surgical intervention has never been exposed to a randomised controlled trial. Therefore, rather than ‘optimum’ debulking enhancing survival, it could be that the ability to achieve the ‘optimum’ is only reflecting the inherent tumour biology of a more chemo-sensitive disease. This debate will continue until such studies are completed.     

Breast cancer among women exposed to polybrominated biphenyls

We conducted a nested case-control study with 1,925 women enrolled in a polybrominated biphenyl (PBB) registry to examine the association between breast cancer and serum PBBs. Twenty women who developed breast cancer were matched to 290 control subjects on sex, race, and age. Women with serum PBB levels of 2.0-3.0 parts per billion (ppb) [odds ratio (OR) = 3.5; 95% confidence interval (CI) = 0.9-13] or 4.0 ppb or greater (OR = 3.1; 95% CI = 0.8-12) had a higher estimated risk for breast cancer than women with less than 2.0 ppb. The odds ratios were unchanged when available breast cancer risk factors were included in the analysis.     

Abdominopelvic CT scan findings after surgery for ovarian cancer

AIMS: To evaluate abdomino-pelvic changes in patients who had total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) for stage I ovarian cancer. METHOD: The postoperative computed tomographic (CT) scans of 23 patients who had undergone TAH and BSO for stage I ovarian tumours between 3 and 14 weeks previously were assessed, providing there had been no treatment with chemotherapy or radiotherapy and that each patient had normal tumour marker (CA125) levels after surgery. After the CT scan patients were followed up and had no clinical or biochemical (CA125) evidence of relapse for a median of 27 months (range 11 to 78 months). The following sites were assessed by two observers: the vaginal vault, round ligaments, bladder, rectum, perirectal fat, pelvic sidewalls, omentum, surgical scar and abdominal wall. Any abnormality was recorded, with re-evaluation on follow-up CT scans in ten patients (between three and 17 months). RESULTS: The following abnormalities were seen: (1) Thickened round ligaments (n=12) with bulbous masses at the surgically transected ends (n=7). This was bilateral in eight patients. (2) Vaginal vault thickening (n=11) either uniform (n=6) or bulbous bilaterally (n=2) or unilaterally (n=3). (3) Subtle omental bed stranding or nodularity (n=11). (4) Peritoneal thickening underlying the scar (n=4). (5) Asymmetrical rectus abdominis muscles (n=3) adjacent to the surgical scar or thickened scar tissue in the anterior abdominal wall (n=4). No significant bladder, rectal, perirectal or nodal abnormalities were found. CONCLUSION: Pseudotumours at the transected ends of the round ligaments, or uniformly swollen round ligaments, may be identified in patients who have had TAH and BSO, as may vaginal vault thickening. Other changes which may be observed in the abdomen and pelvis are peritoneal thickening adjacent to the scar and omental bed stranding.     

Breast cancer risk among women using silicone gel breast implants

Since their introduction in 1962, silicone gel-filled breast implants have been used by an estimated one to two million women. Questions concerning an increased cancer risk to these women have been raised. A review of the medical literature, including case reports, case series, physician surveys, case-control studies, and cohort studies, failed to turn up any evidence which associated the use of silicone breast implants with either an increased risk of breast cancer or an increased risk of a more advanced stage of cancer at the time of cancer diagnosis. The available data do not indicate any significant difference between the characteristics of the breast cancers of women with breast implants and those of women in control populations.     

Clinical features of epithelial ovarian cancer in young reproductive women

A 10-year retrospective review of epithelial carcinoma of the ovary was performed about 95 patients which were diagnosed and treated at the Oita Medical University Hospital. The patients' ages at the first diagnosis ranged from 15 to 85 years with a mean of 51.6 years. Twenty-two of 95 patients (23.2%) were below the age of 40. Most patients analysed in this study complained of lower abdominal pain, lower abdominal mass, and/or lower abdominal fullness. Sixteen of 22 patients under the age of 40 (72.7%) and 27 of 73 patients over the age of 40 (37.0%) were diagnosed as having mucinous cystadenocarcinoma. The incidence of mucinous cystadenocarcinoma below the age of 40 was significantly higher than that over the age of 40 (p < 0.005, chi 2-test). Eleven patients below the age of 40 had FIGO stage Ia grade 1 disease and 2 of these patients were pregnant. The incidence of stage Ia disease under the age of 40 was significantly higher than that over the age of 40 (p < 0.005, chi 2-test). Both pregnant patients and 5 other patients with stage Ia disease were treated with only unilateral salpingo-oophorectomy. All patient with stage Ia disease had no evidence of recurrence within 5 years. This suggests that conservative surgery may be considered as the treatment for the FIGO stage Ia grade 1 ovarian cancer.     

Conservative surgery for stage I ovarian carcinoma in women of childbearing age

OBJECTIVE: To assess the results of a policy of tailored conservative surgical management for young women with stage I ovarian carcinomas. DESIGN: Retrospective study. PARTICIPANTS: Ninety-nine women aged 40 years or younger who underwent either primary surgery in our department or were referred after primary surgery performed elsewhere. METHODS: Of the 99 women in our study, 56 underwent fertility-sparing surgery and 43 more radical surgery. Minimal requirements for conservative management were adequate staging and complete information about the therapeutic options. Factors important in the choice of the treatment were, age, wish to preserve fertility, histologic type and grade, and the stage of the tumour. RESULTS: Conservative treatment was conducted in 84% of nulliparous and in 33% of parous women; 62% of grade 1 tumours, 48% of grade 2, and 50% of grade 3 were treated conservatively. With a median follow up of seven years, we observed five recurrences (9%) of carcinoma in women treated conservatively and five (12%) in those treated more radically. Two women (one in each treatment arm) were saved after recurrence. Two recurrences after conservative surgery involved the residual ovary (3.6%). Two women developed borderline tumour in the contralateral ovary and both were treated by surgery. CONCLUSION: After adequate staging and accurate information is given to the patient, conservative treatment may be safe in some women with early ovarian cancer. The risk of recurrence in the contralateral ovary is low. Conservative surgery may be also considered in some Stage I grade 3 tumours and in some women with stage JC tumours.     

Intra-incisional prophylactic antibiotics for dermatologic surgery

OBJECTIVE: To determine the efficacy of intra-incisional antibiotics in decreasing the risk of wound infections in cutaneous surgery. DESIGN: Prospective, blinded, randomized, placebo-controlled trial conducted during an 8-month period. SETTING: A private practice Mohs micrographic surgery referral center. PATIENTS: Seven hundred ninety consecutive patients referred for Mohs surgery or other dermatologic surgery were randomized to receive anesthesia either with study compound or placebo. The 2 groups were equivalent with respect to age and sex distribution and the lesions treated were similar in character. No patients were withdrawn for adverse effects. INTERVENTIONS: Patients received local anesthesia before surgery with either buffered lidocaine hydrochloride or a solution consisting of nafcillin sodium in buffered lidocaine. MAIN OUTCOME MEASURES: All surgical wounds were evaluated in a blinded fashion at the time of suture removal (5-7 days) and scored according to a standardized assessment chart based on erythema, edema, and the presence of purulent discharge. RESULTS: Seven hundred ninety consecutive patients with 908 surgical wounds were enrolled in this study. A total of 12 wound infections were recorded. Eleven (2.5%) of these occurred in the control group, while only 1 (0.2%) occurred in the nafcillin group. This difference was highly significant (P = .003). Observers were blinded to patient groupings particularly for surgical wound scoring. CONCLUSIONS: This study offers strong supporting data for the use of a single intra-incisional dose of an antibiotic administered immediately before dermatologic surgery. The use of nafcillin and buffered lidocaine solution is inexpensive, safe, convenient, and effective.     

Efficacy of bilateral prophylactic mastectomy in women with a family history of breast cancer

BACKGROUND: Options for women at high risk for breast cancer include surveillance, chemoprevention, and prophylactic mastectomy. The data on the outcomes for surveillance and prophylactic mastectomy are incomplete. METHODS: We conducted a retrospective study of all women with a family history of breast cancer who underwent bilateral prophylactic mastectomy at the Mayo Clinic between 1960 and 1993. The women were divided into two groups - high risk and moderate risk - on the basis of family history. A control study of the sisters of the high-risk probands and the Gail model were used to predict the number of breast cancers expected in these two groups in the absence of prophylactic mastectomy. RESULTS: We identified 639 women with a family history of breast cancer who had undergone bilateral prophylactic mastectomy: 214 at high risk and 425 at moderate risk. The median length of follow-up was 14 years. The median age at prophylactic mastectomy was 42 years. According to the Gall model, 37.4 breast cancers were expected in the moderate-risk group; 4 breast cancers occurred (reduction in risk, 89.5 percent; P<0.001). We compared the numbers of breast cancers among the 214 high-risk probands with the numbers among their 403 sisters who had not undergone prophylactic mastectomy. Of these sisters, 38.7 percent (156) had been given a diagnosis of breast cancer (115 cases were diagnosed before the respective proband's prophylactic mastectomy, 38 were diagnosed afterward, and the time of the diagnosis was unknown in 3 cases). By contrast, breast cancer was diagnosed in 1.4 percent (3 of 214) of the probands. Thus, prophylactic mastectomy was associated with a reduction in the incidence of breast cancer of at least 90 percent. CONCLUSIONS: In women with a high risk of breast cancer on the basis of family history, prophylactic mastectomy can significantly reduce the incidence of breast cancer.     

Breast conservation surgery for breast cancer at a regional medical center

Physical exercise is recommended for the prevention and treatment of osteoporosis. However, its exact role and effectiveness in adulthood is unclear. While vigorous exercise of long duration enhances bone density, few adult individuals comply with such training programs. The present study evaluates the influence of nonphysiological mechanical stimulation, in the form of low intensity vibration (frequency: 50 Hz, acceleration: 2 g, 30 min/day for 5 days/week), on the prevention of bone loss in an animal model of postmenopausal osteoporosis. In the ovariectomised groups of rats a statistically significant (p < 0.05) decrease of bone density (femur and tibia) was recorded at 5 weeks postovariectomy. This effect was maintained for the 12 week duration of the study. Vibration prevented early bone loss after ovariectomy. Vibrated ovariectomised rats showed statistically significantly higher (p < 0.05) BMD values compared to those of their ovariectomised controls at 5 weeks. Vibration did not influence the bone density of the SHAM-operated rats. Although vibration increased ultimate strength (fracture load of the rat femur) in the ovariectomised rats, this finding was not statistically significant. Our data indicate that this method of safe and easily applicable vibration, in the form of a vibrating platform, is effective in preventing early postovariectomy bone loss in an animal model.     

Distress and psychiatric morbidity among women from high-risk breast and ovarian cancer families.

This study assessed psychological distress and psychiatric disorder in high-risk women enrolled in a hereditary breast and ovarian cancer registry, and it evaluated the concordance between self-report data and interview-based psychiatric diagnosis. A sample of 464 women completed the Hopkins Symptom Checklist-25 and were interviewed using modules of the Structured Clinical Interview for DSM-IV. Level of psychological distress and the prevalence of psychiatric disorder were low and in the range that would be expected for a sample of community-residing women. Screening proved inefficient: Less than 10% of distressed women met criteria for a clinical disorder. High-risk women seeking genetic testing in research settings may not require extensive psychological screening and diagnostic assessment. Caution is expressed about possible self-selection biases in women enrolled in hereditary cancer registries. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Breast cancer

The management of patients with breast cancer has been changing over the last few years and this article highlights some areas of particular interest. The changes have been brought about against a background of an increasing disease incidence coupled with increasing political aspirations from patients and their relatives. This paper focuses on organisational aspects of breast cancer care, screening, induction and high-dose chemotherapy, clinical trials, genetics, training of surgical and nonsurgical oncologists and future prospects.
