Sterility of ophthalmic drugs dispensed from spray bottles

We attempted to show that surgical treatment of breast cancer, including axillary lymph node dissection with or without concomitant partial mastectomy (ALND), simple mastectomy (SM), and modified radical mastectomy (MRM) can be performed safely in an outpatient setting. The records of 100 consecutive women undergoing definitive breast cancer surgery by the authors between August 1994 and July 1996 were retrospectively reviewed. Average age was 54 +/- 10 years. Fifty patients were discharged the day of surgery, 44 were hospitalized, and 6 remained 2 or more days postoperatively. Outpatients were more likely to have undergone ALND or SM (42 versus 23 procedures) and more often completed surgery in the morning (36 versus 12); P < 0.05. Eight patients of 35 with MRM were discharged the same day. One patient was readmitted with a wound infection. There were no major complications or deaths. Ninety-four per cent of patients were discharged within 23 hours of surgery; half were discharged the same day. No complications occurred in outpatients, and there were no readmissions. For patients admitted overnight, no complications were detected during the overnight hospital stay. In conclusion, breast cancer surgery, from ALND to SM or MRM, can be safely and comfortably performed on an outpatient basis.     

老年乳腺癌术后多西紫杉醇联合环磷酰胺辅助化疗的毒副作用研究

Objective: The aim of this study was to investigate the side effects of docetaxel with cyclophosphamide as postoperative adjuvant chemotherapy for elderly breast cancer patients. Methods: Thirty-six operable elderly breast cancer patients at intermediate risk based on the St Gallen risk classi.cation underwent modified radical mastectomy and then were given four cycles of TC regimen (docetaxel 75 mg/m2 i.v. on day 1; cyclophosphamide 600 mg/m2 i.v. on day 1; every 21 days ). Primary prophylaxis granulocyte colony stimulating factor (G-CSF) 200μg i.h. was administered on day 4-6. Results: The main side effect was neutropenia. Grade 3 neutropenia developed in 36.1% and G4 in 19.4%, respectively. Most of the other side effects were G1-2. Dose reduction occurred in 11.1% patients. The completion rate of chemotherapy was 100%. Conclusion:Docetaxel with cyclophosphamide as postoperative adjuvant chemotherapy regimen with G-CSF primary prophylaxis is tolerable for elderly patients in general good condition.     

Adjuvant radiotherapy and chemotherapy in node-positive premenopausal women with breast cancer

BACKGROUND: Radiotherapy after mastectomy to treat early breast cancer has been known since the 1940s to reduce rates of local relapse. However, the routine use of postoperative radiotherapy began to decline in the 1980s because it failed to improve overall survival. We prospectively tested the efficacy of combining radiotherapy with chemotherapy. METHODS: From 1978 through 1986, 318 premenopausal women with node-positive breast cancer were randomly assigned, after modified radical mastectomy, to receive chemotherapy plus radiotherapy or chemotherapy alone. Radiotherapy was given to the chest wall and locoregional lymph nodes between the fourth and fifth cycles of cyclophosphamide, methotrexate, and fluorouracil. RESULTS: After 15 years of follow-up, the women assigned to chemotherapy plus radiotherapy had a 33 percent reduction in the rate of recurrence (relative risk, 0.67; 95 percent confidence interval, 0.50 to 0.90) and a 29 percent reduction in mortality from breast cancer (relative risk, 0.71; 95 percent confidence interval, 0.51 to 0.99), as compared with the women treated with chemotherapy alone. CONCLUSIONS: Radiotherapy combined with chemotherapy after modified radical mastectomy decreases rates of locoregional and systemic relapse and reduces mortality from breast cancer.     

Conservation surgery for breast cancer: selection criteria and technical considerations

Patients with stage I or II breast cancer are candidates for either modified radical mastectomy or breast preservation therapy involving limited resection of the primary tumor, axillary dissection, and breast irradiation. The overall survival rates of both these approaches are comparable according to retrospective reviews and ongoing clinical trials, and long-term follow-up confirms the earlier findings. Thus, patients should be given the choice between these two options by surgeons, radiation therapists, and other physicians involved in their care. However, not all breast cancer patients will choose breast preservation surgery, and because of tumor-related and other factors not all patients are candidates. The patient selection criteria are discussed herein and the optimal surgical techniques are reviewed.     

Breast reconstruction for malignant or premalignant disease

In ten patients breast reconstruction was done after surgical treatment for a premalignant or malignant breast disease. In six of these, prophylactic subcutaneous mastectomy and implant reconstruction were carried out, and in the remaining four reconstruction was done after simple or modified radical mastectomy. It is suggested that these procedures should be considered by those physicians and surgeons who undertake evaluation and treatment of breast disease in women. Breast reconstruction should be considered and offered to patients who suffer from the severe personal and emotional trauma attendant to surgical operation for breast disease.     

Phenotypic and molecular characterization of human monoclonal TCR gamma/delta T-cell lines from jejunum and colon of healthy individuals

The treatment of potentially curable carcinoma of the breast has changed from one operation, radical mastectomy, to a flexible approach. At the Cleveland Clinic, we use four types of treatment for primary potentially curable carcinoma of the breast (Stages 0, I and II)--modified radical mastectomy, simple mastectomy, partial mastectomy with postoperative adjuvant radiation therapy and partial mastectomy without radiation therapy. The latter treatment (partial mastectomy without adjuvant radiation) is controversial. We recommend this procedure for patients with T(is) and T1 carcinomas that appear to be localized, without lymph node metastases, Stages 0 and I disease. The overall and disease-free survival rates are similar to those of patients having modified radical or partial mastectomy with radiation. Local recurrence is slightly higher at five years (11.0 percent) as compared with the other procedures, but at ten years, is only 16.1 percent, a figure comparable with patients having partial mastectomy with radiation (14.4 percent). For patients with Stages 0 and I carcinoma of the breast, the addition of postoperative radiation therapy after partial mastectomy seems to be unnecessary.     

Treatment of breast cancer with ipsilateral supraclavicular node metastases

During 1954-1977, among 2803 cases of breast cancer 99 (3.5%) had ipsilateral supraclavicular node mestastases. The results of treatment are reported, based on follow-up for more than 10 years. According to the treatment modality, the patients were divided into 4 groups: I. surgery with postoperative adjuvant chemotherapy and radiation therapy; II. radiation and chemotherapy; III. chemotherapy; IV. no treatment. In group I, surgical procedures consisted of segmental mastectomy in 6; simple mastectomy in 7; modified radical mastectomy in 16; standard radical mastectomy in 12, and extended radical mastectomy in 3. The over-all five-year survival rate was 9%. It was 18% (8/44) in group I, but only 5% (1/21) in group II. None survived for 5 years in group III and group IV. The results seem to indicate that more aggressive multi-modality treatment of breast cancer with ipsilateral supraclavicular lymph node metastases is indicated to expect better survival.     

Immediate, bilateral transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction after mastectomy

Although breast reconstruction has been shown to provide psychological benefits in mastectomy patients, there is reluctance to perform immediate, bilateral TRAM flap reconstruction because of concerns regarding magnitude of the procedure, length of hospitalization, potential complications, and long-term recovery. Between June, 1990 and March 1992, 15 patients underwent immediate, bilateral TRAM flap reconstruction following bilateral mastectomy at the University of Michigan Hospitals. Diagnoses included lobular carcinoma in situ (nine patients), strong family history of breast cancer (five), or bilateral breast cancer (one). Invasive breast cancer was present in three patients. Three modified radical mastectomies and 27 simple mastectomies were performed. Bilateral pedicle TRAM flap reconstruction was carried out at the same time in all patients (30 flaps total). Marginal loss occurred in one flap (3%). Additional complications included marginal necrosis of the abdominal donor site wound (one), wound infection (two), and abdominal donor site hernia (one). Median hospital stay was 7 days. Median follow-up was 13 months (range 4-25 months). All patients have resumed their accustomed pre-operative activity patterns. These findings demonstrate that immediate, bilateral TRAM flap reconstruction is a safe and effective option for breast reconstruction after mastectomy.     

Lymphedema after breast carcinoma. A study of 5868 cases

BASIC PROBLEM AND OBJECTIVE: According to published reports, the incidence of lymphoedema of the arm in patients with cancer of the breast, treated by either surgery or radiotherapy, varies widely. We obtained basic data on the treatment of breast cancer in a large number of patients in order to determine the relationship between the incidence of lymphoedema and the radical nature of the primary treatment. PATIENTS AND METHODS: Data were collected on all women with lymphoedema of the arm after treatment for breast cancer between 1972 and 1995. The increase in arm circumference was measured by a standardised method. Only those patients were included in the final analysis whose arm circumference had increased by at least 2 cm. The type of operation and(or) radiotherapy, tumor histology and TNM classification were recorded. RESULTS: There were 1405 cases of arm lymphoedema after treatment of 5868 cases of breast cancer (24%). 2515 breast cancers had been treated surgically. 3353 surgically and by radiotherapy. Lymphoedema occurred in 22.3% after radical mastectomy without radiotherapy and in 44.4% with it; after modified radical mastectomy without radiotherapy in 19.1%, in 28.9% with radiotherapy; after breast-preserving operation without radiotherapy in 6.7%, with radiotherapy in 10.1%. Until the 1970s radical mastectomy with conventional postoperative radiotherapy has been the treatment of choice, with 38% cases of lymphoedema. This incidence gradually decreased to 16% in subsequent years. CONCLUSION: The incidence of lymphoedema of the arm depends on the radical nature of the primary treatment. The quality of life could be easily improved through minimising the incidence of lymphoedema if current standards of breast-preserving surgery were generally practised.     

Pseudomembranous colitis caused by antibiotics

To study the effectiveness of a trend at the Mayo Clinic toward modifying the standard radical mastectomy, the 5-year survival of 873 women treated surgically for breast cancer from 1965 through 1968 was evaluated. The observed survival of 534 patients treated by the standard radical mastectomy was 85% when nodes were negative and 56% when nodes were positive. For 339 patients treated by the modified radical mastectomy, the observed survival was 80% and 48% when axillary nodes were negative and positive, respectively. In order to accomplish a more significant analysis of cancer risk and results of the two operative procedures, a relatively homogeneous group of 541 patients was established from the total group. In this homogeneous group, the observed survival of 336 patients treated by the standard radical mastectomy was 86% when nodes were negative and 66% when nodes were positive. For 205 patients treated by the modified radical mastectomy, the observed survival was 84% and 66% when axillary nodes were negative and positive, respectively. When patients were further analyzed and compared according to the extent of axillary-node involvement, age at the time of treatment, grade, size, location, and histopathologic type of tumor, and the use of postoperative irradiation, survival was essentially the same, irrespective of the type of mastectomy performed.     

Dose and dose intensity as determinants of outcome in the adjuvant treatment of breast cancer. The Cancer and Leukemia Group B

BACKGROUND: Both total dose and dose intensity of adjuvant chemotherapy are postulated to be important variables in the outcome for patients with operable breast cancer. The Cancer and Leukemia Group B study 8541 examined the effects of adjuvant treatment using conventional-range dose and dose intensity in female patients with stage II (axillary lymph node-positive) breast cancer. METHODS: Within 6 weeks of surgery (radical mastectomy, modified radical mastectomy, or lumpectomy), 1550 patients with unilateral breast cancer were randomly assigned to one of three treatment arms: high-, moderate-, or low-dose intensity. The patients received cyclophosphamide, doxorubicin, and 5-fluorouracil on day 1 of each chemotherapy cycle, with 5-fluorouracil administration repeated on day 8. The high-dose arm had twice the dose intensity and twice the drug dose as the low-dose arm. The moderate-dose arm had two thirds the dose intensity as the high-dose arm but the same total drug dose. Disease-free survival and overall survival were primary end points of the study. RESULTS: At a median follow-up of 9 years, disease-free survival and overall survival for patients on the moderate- and high-dose arms are superior to the corresponding survival measures for patients on the low-dose arm (two-sided P<.0001 and two-sided P = .004, respectively), with no difference in disease-free or overall survival between the moderate- and the high-dose arms. At 5 years, overall survival (average +/- standard error) is 79% +/- 2% for patients on the high-dose arm, 77% +/- 2% for the patients on the moderate-dose arm, and 72% +/- 2% for patients on the low-dose arm; disease-free survival is 66% +/- 2%, 61% +/- 2%, and 56% +/- 2%, respectively. CONCLUSION: Within the conventional dose range for this chemotherapy regimen, a higher dose is associated with better disease-free survival and overall survival.     

A phase II trial and pharmacokinetic analysis of 96-hour infusional paclitaxel in patients with metastatic colorectal cancer

AIMS: To carry out a retrospective study of male breast cancer over a 22-year experience. METHODS: Data from 121 male patients with breast cancer treated between the years 1972 and 1994 at the Surgical Clinic of Ankara Oncology Hospital were reviewed. Distribution of cases according to stage was: 2.5% stage I, 28.9% stage II, 55.4% stage III and 13.2% stage IV (AJCC staging method). The surgical treatment for 23 of the patients (19%) was Halsted's radical mastectomy or modified radical mastectomy. Seventy-three cases (60.3%) had total mastectomy without axillary node dissection and 25 (20.7%) had local tumour excision only. Seventy-two of 121 patients had adjuvant treatment. RESULTS: In general the prognosis of men with breast cancer was worse than for women. In the analysis of patients in stages I, II and III-A (operable disease group), the 5-year survival rates were 73% in axillary node-negative patients and 77% in those with tumours sized under 5 cm (P<0.001). In these patients, univariate analysis demonstrated that axillary status (relative risk of death in positive status vs. negative=3.6), tumour size (relative risk in T3 vs. T1-2=2), surgical treatment type (relative risk in simple mastectomy vs. radical mastectomy=1.9) and adjuvant chemotherapy (relative risk if no chemotherapy=1.4) were statistically significant factors associated with survival. CONCLUSIONS: Cox's regression model revealed that axillary status, tumour size and type of surgical treatment were the most important independent prognostic factors (P<0.001).     

Evaluation of dissection of the axilla in modified radical mastectomy

Fifty consecutive unselected patients with infiltrating carcinoma of the breast underwent radical mastectomy in two consecutive stages. The initial operation was a modified radical mastectomy, with preservation of the pectoral muscles, and the second stage, a procedure to transform the initial operation into a standard radical mastectomy. An analysis of the location and the number of the lymph nodes recovered in the two stage operation shows that a so-called modified radical mastectomy is inadequate to ensure the clearing of the axilla. Lymph nodes were recovered at the second stage of the operation in 36 patients, and seven of these patients had metastasis. Modified radical mastectomy was effective in erradicating the lymph nodes of the lower part of the axilla but inadequate for lymph nodes at levels II and III and, especially, the interpectoral lymph nodes.     

Radiotherapy for post-operative inflammatory breast cancer

Two patients with inflammatory breast cancer treated with a combination of radical mastectomy, irradiation, and immunochemotherapy are reported. After radical mastectomy, both patients were given a dose of 4000 rad and 5000 rad to the chest wall and parasternal lymph nodes, and 5000 rad to the axillary and supraclavicular lymph nodes. However, both patients died of recurrence within the irradiated field of the chest wall and metastatic spread to the neighbouring skin. A discussion on the dose and field in radiation therapy for inflammatory breast cancer is presented.     

Randomised controlled trial of effects of early discharge after surgery for breast cancer

OBJECTIVE: To determine the effect of early discharge from hospital after surgery for breast cancer on physical and psychological illness. DESIGN: Randomised controlled trial comparing discharge two days after surgery (before removal of drain) with standard management (discharge after removal of drain). SETTING: Regional breast unit. SUBJECTS: 100 women with early breast cancer undergoing mastectomy and axillary node clearance (20) or breast conservation surgery (80). MAIN OUTCOME MEASURES: Physical illness (infection, seroma formation, shoulder movement) and psychological illness (checklist of concerns, Rotterdam symptom questionnaire, hospital anxiety and depression scale) preoperatively and at one month and three months postoperatively. RESULTS: Women discharged early had greater shoulder movement (odds ratio 0.28 (95% confidence interval 0.08 to 0.95); P = 0.042) and less wound pain (odds ratio 0.28 (0.10 to 0.79); P = 0.016) three months after surgery compared with women given standard management. One month after surgery scores were significantly lower on the Rotterdam symptom questionnaire in patients who were discharged early (ratio of geometric mean scores 0.73 (0.55 to 0.98) P = 0.035), but rates of psychological illness generally did not differ between groups. CONCLUSIONS: Increased rates of physical or psychological illness did not result from early discharge after surgery for breast cancer. This policy can be recommended for patients with support at home.     

Estimating mechanical blood trauma in a centrifugal blood pump: laser Doppler anemometer measurements of the mean velocity field

There are different opinions on the duration of post-operative shoulder immobilisation following arthroscopic repair of labrum tears. Between 1993 and 1994 at our department arthroscopic repairs of the glenoid labrum as described by Habermeyer (15, 16) have been performed in 38 patients. In 20 of these patients postoperative treatment included immobilisation of the operated shoulder in a Gilchrist-bandage for 3 weeks, while in the remaining 18 patients this postoperative immobilisation period was decreased to only 1 or 2 weeks. Physiotherapy started the day after the operation, using a device for passive-motion exercises. The mean follow-up time of our examinations was 15.4 month. The mean score by Rowe rose significantly from 20.0 preoperatively to 82.6 at the follow-up examination. Results were excellent or good in 89.4% of all cases, new shoulder dislocations did not occur in any case. Patients having their shoulders immobilised for 3 weeks reached significantly higher Rowe-scores at our follow-up than those patients, whose shoulders were immobilised for only 1 or 2 weeks. Therefore, postoperative management following arthroscopic repair of labrum tears should include immobilisation of the operate shoulder for 3 weeks and an early start of passive-motion exercises.     

Primary vitrectomy for bullous rhegmatogenous retinal detachments due to complex breaks

Sixty-five patients who underwent modified radical mastectomy were compared with 55 breast conservation patients, all of whom were in stage I, II or III of breast cancer and were under treatment at an oncology clinic in northern Israel. The main findings indicate no differences between the groups in physical, psychosocial, marital or medical interaction, according to the CARE scale. These findings reflect the results of similar comparative studies conducted during the 1980s and 1990s as documented in the literature. Sexual interaction showed statistical differences favoring the women who had undergone mastectomies.     

Autonomous thyroid adenoma, papillary thyroid carcinoma, and ectopic parathyroid adenoma in a patient with primary hyperparathyroidism and a nontoxic multinodular goiter

OBJECTIVE: To discuss the method for nipple-areola preserved mastectomy with one-stage breast reconstruction in cancer surgery. METHODS: Because of the merits of sufficient blood supply and plasticity of rectus abdominis musculocutaneous flap, we used one-stage breast reconstruction after modified radical mastectomy. The incision line was covered and the nipple-areola was preserved. The reconstructed breast was naturally in contour. RESULTS: 21 cases were treated from 1990 to 1995, and 18 of them received horizontal-rhombus shaped rectus abdominis musculocutaneous flaps and 3 longitudinal-rhombus flaps for breast reconstruction. Nipple-areola was preserved in 16 cases. Objective evaluation after operation showed that the excellent and satisfied rate reached to 90.5%; and subjective evaluation showed that the excellent and satisfied rate reached to 95.2%. Thirteen cases have been followed up for 3 years, and 9 for 5 years. Three-year survival rate was 100% (13/13), and 5-year 88.9% (8/9). CONCLUSION: The method is recommendable for the treatment of stage I-II breast cancer.     

Changes in the treatment outcome of node-positive breast cancer stratified by menopausal status: comparison of patients treated in 1965-75 versus those treated in 1976-86

OBJECTIVE: The objective of this study was to examine whether and to what extent the outcome of treatment for lymph-node positive breast cancer patients improved between the periods 1965-75 and 1976-86. METHODS: The subjects were 1595 patients with breast cancer positive for lymph node metastasis who were treated at the National Cancer Center Hospital between 1965 and 1986. In order to analyze background factors and treatment outcome, we classified the patients into four groups stratified by the time of initial surgery (1965-75/1976-86) and menopausal status (premenopause/postmenopause). RESULTS: With respect to the clinicopathological background factors, significant changes between the periods 1965-75 and 1976-86 were more frequent use of modified radical mastectomy and postoperative adjuvant chemoendocrine therapy and less frequent use of postoperative radiotherapy in both pre- and postmenopausal patients. The 10-year disease-free and overall survival rates improved by approximately 15-20% between 1965-75 and 1976-86 in this group of patients, regardless of menopausal status. CONCLUSION: The patients with node-positive disease treated at our hospital showed an increase in both disease-free and overall survival from 1965 to 1986.
