The ability of adjuvant radiotherapy to prevent distant metastasis and to prolong survival in patients with early breast cancer is much debated. The paper presents a joint analysis of long-term results (13-16 years' follow-up) from the Oslo and Stockholm randomised trials of post-operative megavoltage radiotherapy versus surgery alone. Among node-positive patients there was a significant 37% relative reduction of distant metastases with radiation (P less than 0.01) and an overall survival difference in favor of the irradiated patients which corresponded with a 22% relative reduction of deaths of borderline significance (P less than 0.06). No significant benefit with radiation in terms of distant metastasis-free survival or overall survival was observed among node-negative patients. The results show that effective local treatment can prevent distant dissemination in some patients and contradict the contention that node-positive breast cancer invariably is a systemic disease already at primary diagnosis.

The designation of the obstetrician-gynecologist as a principal physician for women may impose new responsibilities on them, but in reality it merely reaffirms what most obstetrician-gynecologists have long regarded as standard practice. The gynecologist has always insisted that breast examination is an integral part of the evaluation of every patient and the basic knowledge of breast disease is certainly as essential as any understanding of obstetric and gynecologic problems. The obstetrician-gynecologist should follow certain guidelines that will help achieve in making an early diagnosis. These include: Integrate breast examination into the routine gynecologic examination of all patients. Instruct patients in the technique of life-long, periodic breast self-examination. Develop proper ambulatory surgical facilities suitable for performing breast biopsies. Perform biopsy for all true, solid, three-dimensional masses. The final diagnosis of pathologic condition rests on a careful histologic examination of a biopsy specimen. Encourage research, both basic and clinical, and etiology, diagnosis and treatment of breast lesions including innovative screening programs for high risk patients. Include obstetric and gynecologic residency programs with specific instructions in early breast cancer detection techniques. Previously, breast cancer was viewed as a stereotype disease that progressed from the breast to the nodes to the systemic area. This has changed. Breast cancer is now viewed as a systemic disease, which spreads to local and distant sites at the same time. Breast cancer is best viewed as occultly metastatic at the time of presentation. Therefore, dissemination of tumor cells has occurred by the time of surgery in many patients, and it is not surprising that radical mastectomy and local irradiation do not prevent metastatic disease.

One-hundred-and-seventy-one patients with invasive lobular carcinomas have been matched with 342 patients with non-lobular invasive carcinomas for lymph node stage, tumour differentiation and patient age on a one to two basis. The two groups were investigated for differences in prognostic factors, survival, disease-free interval, metastatic patterns, receptor status, response to endocrine therapy after distant metastases and bilateral cancer rates. Patients with lobular carcinomas survived significantly longer than patients with carcinomas of no specific type, particularly in survival from the time of diagnosis of distant metastases; lobular carcinomas more often responded to endocrine treatment for systemic disease. Lobular cancers had a significantly higher rate of local recurrence, particularly after treatment by excision and breast irradiation. No differences were found between the two groups with respect to regional or distant recurrence rates, distant organ involvement patterns, distant metastatic free intervals and receptor status. Bilateral cancer was more frequent in patients with lobular carcinoma.

T expaanded role of the surgeon now integrates a range of multi-modality treatment options that address both local and regional and systemic disease control. This decision-making process requires an understanding of the natural history of cancer and those prognostic factors that predict the risk of clinically occult regional metastases and distant metastases. The goal in managing the surgical patient with cancer is a full implementation of multi-disciplinary cancer care to provide the highest quality of care with the maximum rehabilitation at the lowest possible cost.

Between May 1985 and December 1988, 41 patients were treated palliatively with endoscopic neodymium:yttrium-aluminum-garnet laser therapy for obstruction of the esophagus by malignant disease. All were considered incurable, because they presented with distant metastases, severe systemic disease, extensive local disease or recurrent disease. Thirty-nine percent were managed as outpatients; the remainder required admission to hospital. Sixty-three percent of the outpatients had adenocarcinoma, and 31% had squamous cell carcinoma; over 90% of the tumours were less than 8 cm long, and 63% were in the distal one-third of the esophagus or the cardia. Forty-four percent of the inpatients had adenocarcinoma, and 44% had squamous cell carcinoma; in this group, over 90% of the tumours were less than 8 cm long, and 56% were in the distal one-third of the esophagus or the cardia. The mean number of sessions and laser energy administered were 2.6 and 4949 J for outpatients and 2.7 and 4974 J for inpatients. Palliation of dysphagia was good to excellent in all outpatients but was not as good for the inpatient group, in which one major complication occurred. The mean length of survival for outpatients and inpatients was 6.3 months (range from 1 to 16 months) and 3.9 months (range from 1 to 18 months) respectively.

Between December 1985 and August 1988, there were 115 patients at 13 centers who were entered on a randomized comparison of tetracycline and bleomycin for treatment of malignant pleural effusions. Fifteen patients were not treated, primarily due to rapid progression of systemic cancer. Fifteen patients entered on a high-dose regimen of bleomycin (120 units) were excluded from this analysis (following early closure of that arm), leaving 85 patients randomized to low-dose bleomycin (60 units; 44 patients) or tetracycline (1 g; 41 patients). Patients were required to have a cytologically positive pleural effusion, good performance status (0, 1, or 2), lung reexpansion following tube thoracostomy with drainage rates of 100 ml/24 or less, no prior intrapleural therapy, no prior systemic bleomycin therapy, no chest irradiation, and no recent (four weeks) change in systemic therapy. A total of 11 patients (five with bleomycin and six with tetracycline) were not evaluable due to technical problems with tube drainage (one), loss to follow-up (two), sudden death due to pulmonary embolus (one), and rapid progression of systemic disease (seven). There were no clinically significant differences in demographic factors, primary site, performance status, or presence of metastases other than pleural effusion. Overall survival did not differ between the two groups. Median time to recurrence or progression of the effusion was 32 days for tetracycline-treated patients and at least 46 days for bleomycin-treated patients (p = 0.037). The recurrence rate within 30 days of instillation was 36 percent (10/28) with bleomycin and 67 percent (18/27) with tetracycline (p = 0.023) (not all patients were restudied in the first 30 days). By 90 days the corresponding recurrence rates were 30 percent (11/37) for bleomycin and 53 percent (19/36) for tetracycline (p = 0.047). Toxicity was similar between groups.

Central retinal artery occlusion (CRAO) is uncommon in those younger than 50. We present a 42-year-old man who complained of sudden loss of vision in the left eye. Fundus examination showed typical findings of CRAO. Extensive medical work up showed no evidence of diabetes or of cardiovascular, hematologic or collagen disease. However, a malignant tumor of the right testis was found, with metastases in the lung, retroperitoneal lymph nodes and brain. The right testis was resected and chemotherapy and brain irradiation resulted in remission during a follow-up of 2.5 years. The differential diagnosis of CRAO in younger patients is difficult. We believe that metastases from the primary tumor were the cause of CRAO in our patient. The possibility of malignancy with metastatic spread causing CRAO should be considered, particularly in relatively young patients with no other evidence of systemic disease.

Brain metastases from colorectal carcinomas are very uncommon and are almost uniformly seen in the setting of advanced, systemic disease. We describe a unique case of multiple, isolated brain metastases occurring from a Duke's B carcinoma of the sigmoid colon. Careful staging at two intervals at which clinical brain metastases were found did not disclose additional evidence of systemic disease. The cascade mechanism thought to be involved in the development of systemic metastases is reviewed, and a possible alternate route is suggested for direct access by tumor cells to the brain via Batson's vertebral plexus.

The authors evaluated 5623 cases of primary breast cancer followed for 1 to 21 years. Overall and breast cancer death rates were determined and compared to expected rates. Breast cancer patients showed overall and breast cancer death rates significantly higher than expected and which persisted at long-term follow-up. The observed/expected overall death ratios for follow-up periods of 0-5, 6-10, 11-15 or 16-20 years were 3.61, 2.55, 1.60 and 2.11, respectively. Death rates from breast cancer at 5, 10, 15 and 20 years were 20%, 32%, 40% and 48% respectively. The evidence of a persistent excess mortality even after long-term follow-up suggests the hypothesis that breast cancer is a systemic disease when clinically diagnosed. This study provided no evidence of a "clinical" cure for breast cancer patients. Even for N- patients the 5, 10, 15 and 20 year death rates from breast cancer were 12%, 20%, 28% and 38%, respectively. N- breast cancer, which is currently considered as a localized disease cured by surgery in most cases, would be better regarded to as a slow-growing metastatic disease, although "personal" cure may be achieved in many subjects dying of causes other than breast cancer.

Twenty-three patients with advanced or recurrent breast cancer involving bony chest wall were treated by extended full-thickness chest wall resection and immediate reconstruction. The results were as follows: 1) Distant metastases were found concurrently or subsequently in more than half of the patients. Therefore, we should regard chest wall lesions as a systemic disease. 2) Long term result was encouraging, with 73.9% local control rate. 3) Post-surgical prognosis of the patients with sternal metastasis and solitary chest wall lesions were favorable, in that order. 4) Both local control rate and survival of the patients with mediastinal invasion, however, were fairly poor. 5) Disease-free interval (D.F.I.) after mastectomy longer than 5 years correlated significantly with a long survival after chest wall resection. As a result, we confirmed that chest wall resection was the treatment of choice for the patients with long D.F.I. and solitary chest wall lesion without mediastinal invasion nor metastasis, but the postoperative systemic therapy was indispensable to improve the patient's survival.
