Hormone conditioned cancer chemotherapy for recurrent breast cancer prolongs survival

Left suprarenal-inferior mesenteric venous shunt (Inokuchi) was prescribed for 80 patients with recurrent breast cancer and the efficacy of hormone conditioned cancer chemotherapy was assessed. The patients were separated into 3 groups according to the historical regimen of combined chemotherapy: Group I; surgical hormone therapy alone, Group II; surgery plus short term chemotherapy, and Group III; surgery plus long term chemotherapy. The 5 year survival rate of the responsive patients to the surgical hormone therapy was as high as 84.6 per cent in Group III, as compared to that of Groups I and II, 41.7 per cent and 16.7, respectively. Survival was not prolonged in non-responsive patients, regardless of the group. These findings indicate that surgical hormone therapy combined with postoperative long term cancer chemotherapy is a valid and effective method for treating recurrence of breast cancer.     

Ten-year survival rates in breast cancer using combination chemotherapy.

The outcome in 254 patients with all stages of breast cancer treated by combination chemotherapy is presented. All the patients were treated 10 or more years ago. The 10-year survival rate for Stages I and II combined is 60 per cent, in Stage III 19 per cent and in Stage IV 3 per cent. The combined rate in Stages I and II differed markedly according to hormonal status. In premenopausal patients the rate was 84 per cent compared with 42 per cent in postmenopausal patients.     

Neoadjuvant chemotherapy in stage III breast cancer

Neoadjuvant chemotherapy in advanced breast cancer can potentially downstage disease prior to definitive surgery. In this study, a doxorubicin-based neoadjuvant regimen was administered to stage III breast cancer patients to assess 1) primary tumor response, 2) tumor involvement of resection margins, and 3) predictive value in cancer outcome. Eighty-two patients with stage IIIA and IIIB breast cancer diagnosed between 1990 and 2003 were studied. All patients received similar chemotherapy regimens, consisting of doxorubicin, cisplatin, and 5-fluorouracil, plus surgery and radiation therapy. End points measured include primary tumor response [complete response (CR) = 100%, partial response (PR) > 50%, or no response (NR) < or = 50%], resection margins for tumor, disease-free, and overall survival. Kaplan-Meier and log-rank tests were performed. Of the 82 patients studied, 34 received neoadjuvant therapy, 48 received conventional postoperative treatment. Seventy-two per cent of the stage IIIB and 22 per cent of the stage IIIA patients received neoadjuvant therapy. In the neoadjuvant group, 29 (85%) patients demonstrated tumor response, 9 (26%) of which were CR. Tumor-free resection margins were achieved in 94 per cent of the neoadjuvant group. Survival analysis demonstrated no benefit comparing neoadjuvant versus postoperative adjuvant therapy but hints at improved disease-free survival in neoadjuvant CR patients (log-rank test, P = 0.07). Eighty-five per cent of patients with stage III breast cancer treated with neoadjuvant chemotherapy experienced clinical response, with 26 per cent CR, and 97 per cent tumor-free resection margins. CR may portend a better cancer outcome.     

Metaplastic breast cancer: clinical features and outcomes

Metaplastic carcinoma of the breast, a neoplasm with both epithelial and mesenchymal elements, represents less than 1 per cent of all breast cancer. We reviewed the records of all patients diagnosed with localized metaplastic breast cancer from 1991 to 2003 at our institution. We identified 21 patients. Mean primary tumor size was 4.62 cm. Eight patients (38%) had axillary node involvement at presentation. All the tumors were high grade. Only two (10%) of the tumors were hormone receptor positive. Seventeen (81%) of the patients received adjuvant chemotherapy, and 12 (57%) of the patients received radiation. Ten (29%) patients suffered a local recurrence. With a mean follow-up of 46 months, the 5-year disease-free and overall survival was 42 per cent (95% CI: 20% to 65%) and 71 per cent (95% CI: 46% to 96%), respectively. Stage-specific overall survival was 100 per cent, 83 per cent, and 53 per cent for stages I, II, and III, respectively. By multivariate analysis, there was no impact on recurrence or survival with regard to size, age, menopausal status, nodal status, histologic subtype, adjuvant therapy, or extent of surgery. Metaplastic breast cancer is a unique neoplasm that tends to present at an advanced stage and has a propensity for local recurrence. When stratified by stage, however, survival appears similar to that of adenocarcinoma of the breast, and these tumors should be treated as such.     

The Integrated Evaluation of the Results of Oncoplastic Surgery for Locally Advanced Breast Cancer

The optimal surgical management of locally advanced breast cancer (LABC) remains undefined. The aim of the study was to obtain long‐term results of oncoplastic surgery in terms of overall survival, loco‐regional recurrence, and quality of life in case of LABC. Prospective cohort study enrolled 60 patients with stage III breast cancer. Forty‐two (70%) patients received neo‐adjuvant chemotherapy, 28 patients were considered suitable for surgery as initial treatment option. Type II oncoplastic surgery was performed for all patients: hemimastectomy and breast reconstruction with latissimus dorsi flap – for 29 (48.3%), lumpectomy – 31 (51.7%), and reconstruction with subaxillary flap for four (6.7%), with bilateral reduction mammoplasty – 14 (23.3%) and with J‐plastic – 13 (21.7%) patients. Adjuvant chemotherapy and hormonal therapy followed surgery for all, except one, patients. Sequential radiotherapy was administered for all patients. The mean period of follow‐up was 86 months. Postoperative morbidity rate was 5%. Local‐regional recurrence was detected in six (10%) patients. After reoperation no local relapse was diagnosed. However, three of these patients had systemic dissemination of the disease. Distant metastasis was detected in 23 (38.3%) patients. Distant metastasis‐free survival at 5 years was 61.7%. Fourteen patients died (23.3%). A total of 87.2% of the patients had good and excellent esthetic outcome. Oncoplastic breast‐conserving surgery can be proposed for selected patients with LABC with acceptable complication, local recurrence rate, and good esthetic results.     

Contemporary management of breast cancer during pregnancy and subsequent lactation in a multicenter cohort of young women with breast cancer

The incidence of breast cancer diagnosed during pregnancy is increasing. We sought to characterize patient, treatment, pregnancy and lactation factors among young women with newly diagnosed breast cancer during pregnancy in a prospective cohort study. We identified all women who were pregnant when diagnosed with invasive breast cancer among those enrolled in the Young Women's Breast Cancer Study (NCT01468246), and collected details on pregnancy, birth and lactation from surveys, and treatment information medical record review. Of 1302 enrolled participants, 976 women with invasive breast cancer completed full baseline surveys, among whom 39 (4.0%) patients reported being pregnant at diagnosis. Median age at diagnosis was 34 years (range: 25‐40), with stage distribution: I, 28%; II, 44%; III, 23%; and IV, 5%. 74% of patients (29/39) had grade 3 tumors, 59% (23/39) ER‐positive, and 31% (12/39) HER2‐positive disease. 23 (59%) had surgery during pregnancy, 4 (17%) during the first trimester. Among the women who had surgery during pregnancy, 61% (14/23) underwent lumpectomy, 35% (8/23) unilateral, and 4% (1/23) bilateral mastectomy. All patients who had chemotherapy (51%, 20/39) received it in second and third trimesters, and had ACx4. There were 31 live births, 2 spontaneous, and 5 therapeutic abortions. Among live births, 16 (41%) were before 37 weeks of gestation. Three women reported breastfeeding. Within 6 months after delivery, comprehensive staging in 13 patients showed upstaging in four patients. In a contemporary cohort of young women with breast cancer, pregnancy at diagnosis is relatively uncommon. Treatment during pregnancy can generally be consistent with standard surgical and chemotherapy approaches, with attention to timing of therapies. Longer‐term outcomes including effects of some timing issues including delayed use of anti‐HER2 therapy on patient outcomes warrant further research.     

The follow up study of intra-arterial infusion chemotherapy with local vein blocking as a surgical neo-adjuvant treatment for locally advanced breast cancer

Preoperative intra-arterial infusion neo-adjuvant chemotherapy, in combination with local vein blocking, was administered to thirtyone patients with locally advanced stage III breast cancer. The anti-cancer drugs and dosages used were 500 mg of 5-Fluorouracil (5FU), which was infused daily for 7–14 days, and 20 mg of Adriamycin (ADM), which was administered as a bolus dose twice into the subclavian and internal mammary arteries. The response rate of this method on the primary tumor was 48.4 per cent, and, histologically it was found to be as high as 90.3 per cent. The response rate of the clinical effects on the regional lymph nodes was 50.0 per cent, however, histologically, it was found to be lower than that of the primary tumor. In the long-term follow up study the 5-year survival rate was 72.2 per cent. Thus, this method seems to be effective as a combined modality in cases of locally advanced stage III breast cancer.     

Pathologic Tumor Response of Invasive Lobular Carcinoma to Neo‐adjuvant Chemotherapy

Abstract: Neo‐adjuvant chemotherapy is used for locally advanced breast cancer patients with significant variation in tumor response. Our objective is to determine the clinicopathologic effect of neo‐adjuvant chemotherapy on invasive lobular carcinoma. A review of a single‐institution data base of women diagnosed with breast cancer identified 30 patients from 1999 to 2009 with operable invasive lobular carcinoma who received neo‐adjuvant chemotherapy. Patient demographics and clinicopathologic data were reviewed. Cases were reviewed by a single pathologist (NNE). Residual cancer burden class was determined for each case. Median patient age was 50 years (range 25–79). All tumors were hormone receptor positive and clinical stage II or III carcinomas. Most patients (53.3%) had combination anthracycline‐ and taxane‐based chemotherapy. Therapy‐related changes were noted within the tumor bed in 25 (83.3%) patients. Six (30%) of 20 patients with residual axillary disease had therapy‐related nodal changes. There were 11 patients with moderate residual disease (class II) and 18 (60%) with extensive (class III); there were no complete pathologic responses (class 0). Only one patient (3.3%) converted from mastectomy to breast‐conserving surgery. Four (13.3%) patients developed distant metastases; all had pleomorphic‐type, clinical stage III tumors with residual cancer burden III classification and developed distant disease in the 2 years after surgery (range 0–26 months). Median follow‐up time was 29.5 months (range 7–132). Patients with locally advanced pleomorphic‐type lobular carcinoma appear to develop early post‐treatment metastatic disease. Neo‐adjuvant chemotherapy did not appear to have significant impact on the surgical treatment of patients with invasive lobular carcinoma.     

Five year results of radical mastectomy for breast cancer,by a sternal splitting,intrapleuralen bloc resection of the internal mammary lymph nodes

A new operative method of extended radical mastectomy enables complete resection of the axillary and internal mammary lymph nodes. In this paper, we present the histological analysis of the internal mammary involvement, and the estimated 5 year survival rate, of 100 patients with breast cancer of Stage I, II or III, who underwent this operation. The incidences of axillary and internal mammary involvements were 41 per cent and 17 per cent, respectively. The metastases in the internal mammary lymph node chain were located from just below the supraclavicular vein to the third intercostal space along the internal mammary vessels. The types of lymphatic invasion observed in the internal mammary chain were lymph node metastases in 88 per cent, metastatic lesion in the lymphoid tissue in 29 per cent and cancer cell emboli in the lymphatic channel in 71 per cent. The overall estimated 5 year survival rate was 90.5 per cent. Where there was internal mammary involvement, the estimated 5 year survival rates for those with no axillary lymph node metastasis, those with fewer than 3 metastatic axillary lymph nodes, and those with more than 4 metastatic axillary lymph nodes were 100 per cent, 80 per cent and 31.2 per cent, respectively. Although the assumption that more aggressive surgical removal of the primary lesion and the regional lymphatic spread gives a higher cure rate has not been proved, this extended radical mastectomy with adjuvant chemoendocrine therapy seems to give a higher 5 year survival rate for patients with internal mammary involvement.

An analysis of filtration and volume of radionucleotide in sentinel lymph node biopsy in breast cancer patients

Controversy has occurred regarding whether to filter or not to filter the radionucleotide and what the optimal volume is when performing sentinel lymph node biopsies. To try and resolve this question we retrospectively looked at sentinel-node biopsies for breast cancer performed at our institution over an 18-month period. One hundred seven patients underwent sentinel node biopsy. Ninety-four patients had an axillary-node dissection. Twelve patients did not have a nodal dissection based on National Surgical Adjuvant Breast and Bowel Project protocol, and one patient refused dissection. Patients fell into three groups: Group I, filtered 8 cm3; Group II, unfiltered 8 cm3; and Group III, unfiltered 16 cm3 (NSABP protocol). Sentinel nodes were identified in 96.3 per cent of Group I, 84.9 per cent of Group II, and 96.3 per cent of Group III. These groups were not statistically different. With the addition of blue dye the ability to identify the sentinel lymph node was for Group I 96.3 per cent, for Group II 96.2 per cent, and for Group III 100 per cent. The false negative biopsy result was 0 per cent for all groups. The patients receiving 16-cm3 volume complained about a greater level of discomfort compared with the lower-volume patients. In conclusion neither the volume nor the filtration process affected the surgeon's ability to find the sentinel lymph node or the false negative rate. The higher injection volumes resulted in more pain. The costs and radiation exposure of the filtration process are not warranted.     

Improved staging for testicular cancer using biologic tumor markers: a prospective study

The effective use of surgery, chemotherapy and radiation therapy for patients with testicular cancer requires accurate staging for therapy and/or interpretaton of end results. The conventional staging parameters, including the lymphangiogram, inferior venacavogram and excretory urogram, often yield a considerable staging error. With sensitive and specific radioimmunoassays of serum alpha-fetoprotein and human chorionic gonadotropin in 118 patients with embryonal carcinoma with or without teratoma undergoing clinical and surgical staging the staging errors have decreased to 9 to 14 per cent in stage I and 5 to 10 per cent in stage II cases. Various clinical observations have been made in this group of patients: 1) persistently elevated serum markers after orchiectomy for testicular cancer invariably indicate stage II or III disease, 2) persistently elevated serum markers after positive lymphadenectomy usually suggest stage III disease and 3) persistently elevated serum markers after lymphadenectomy negative for tumor invariably indicate stage III disease. Therefore, such determinations are important guides to further therapy and must be an essential feature of adjuvant trials.     

Immediate breast reconstruction for stage III breast cancer using transverse rectus abdominis musculocutaneous (TRAM) flap

Background: The management of stage III breast cancer is challenging; it often includes multimodal treatment with systemic therapy and/or radiation therapy and surgery. Immediate breast reconstruction has not traditionally been performed in these patients. We review the results of immediate transverse rectus abdominis musculocutaneous (TRAM) flap in 21 patients treated for stage III breast cancer. Methods: Data have been collected retrospectively on 21 patients diagnosed with stage III breast cancer between 1987 and 1994. All patients had mastectomy and immediate TRAM reconstruction. Thirteen patients received primary systemic therapy, 10 patients received postoperative consolidation radiotherapy to the operative site, and 3 patients received preoperative radiation. Results: Mean follow-up for the group was 26 months. Two patients died with disseminated disease: neither of them developed local disease recurrence in the operative site; 82% of the patients followed for at least two years are free of disease. Sixty-two percent of the patients received preoperative chemotherapy, the remaining patients received postoperative multiagent chemotherapy and/or radiation therapy. Two of the patients received autologous bone marrow transplants after their adjuvant therapy. Ten patients had postoperative radiotherapy for consolidation; three patients received preoperative radiation. Conclusions: Immediate TRAM reconstruction for stage III breast cancer is not associated with a delay in adjuvant therapy or an increased risk of local relapse. It facilitates wide resection of involved skin without skin grafting. Radiation therapy can be delivered to the reconstructed breast when indicated without difficulty. Breast reconstruction facilitates surgical resection of stage III breast cancer with primary closure and should be considered if the patient desires immediate breast reconstruction.Results of this study were presented at the 48th Annual Cancer Symposium of The Society of Surgical Oncology, Boston, Massachusetts, March 23–26, 1995.     

Community-based assessment of adjuvant hormone therapy in women with breast cancer, 1991-1997

This study used population-based tumor registry data to describe the patterns of adjuvant hormone therapy and to examine the correlates of hormone therapy for women with breast cancer. The study population included 5101 women (age 20 years) who were diagnosed with breast cancer in 1991 through 1997 in the entire state of New Mexico. Overall, 32% of women with stage I, II, or IIIA breast cancer received adjuvant hormone therapy. The likelihood of receiving adjuvant hormone therapy increased with tumor stage at diagnosis. Women less than 50 years of age were significantly less likely to receive adjuvant hormone therapy compared to those age 50 to 54 years, but there was no significant difference in the use of adjuvant hormone therapy for women age 55 years and older. The use of adjuvant hormone therapy was influenced by hormone receptor status and lymph node status. Patients who received adjuvant chemotherapy were also more likely to receive adjuvant hormone therapy than those who did not. The use of adjuvant hormone therapy alone was relatively stable over time and the use of adjuvant chemotherapy alone increased, but the receipt of chemotherapy combined with hormone therapy decreased from 1991 to 1997. There was no significant difference with age in the use of adjuvant hormone therapy among 55-year-old women compared to those age 50 to 54 years, whereas women less than 50 years of age were significantly less likely to receive this therapy. The use of adjuvant hormone therapy varied significantly by tumor stage, lymph node status, hormone receptor status, and the receipt of adjuvant chemotherapy.     

Treatment of early breast cancer, a long-term follow-up study: the GOCS experience

Most cases of breast cancer are diagnosed at early stage of disease; therefore, treatment is oriented to increase the disease-free interval (DFI) and overall survival (OS). The prognosis, in comparison with other malignancies, has improved in the last decades as a result of mammographic screening. The aim of the study was to report the incidence of local and distant recurrence, DFI and OS in patients (pts) with stage I and stage II breast cancer over a period of 26 years divided into three groups. From January 1978 to December 2004, 927 women with early breast cancer (EBC) were included, 350 were stage I and 577 Stage II (AJCC 2002). Patients were divided according to the year of diagnosis into three periods of 10 years: Group A (1978-1987) 135 pts, Group B (1988-1997) 412 pts, and Group C (1998-2004) 380 pts. DFI was analyzed from the date of initial diagnosis to the date of local or distant recurrence. OS was estimated from the date of initial diagnosis to the last follow-up or date of death. Median age was 51 years (28-92). Conservative surgery was performed in 69% of pts, adjuvant radiation therapy in 78%, adjuvant chemotherapy in 29%, and adjuvant hormone therapy in 18%. The median follow-up was 8.4 years (0.3-30). The mean tumor size in Group A was 2.7 cm, in Group B 2.2 cm, and in Group C 1.94 cm (p = 0.0001). The percentage of pts with stage I increased from 13% in Group A to 38% in Group B and to 47% in Group C (p = 0.0001). Local recurrence was documented in 5% of all pts, whereas 28% developed metastatic disease. The DFI and OS showed a statistically significant difference among the three groups (p = 0.005). DFI rate at 5, 10, 15, 20, and 25 years was 71%, 67%, 65%, 65%, and 64%, respectively. OS at 5, 10, 15, 20, and 25 years was 82%, 62%, 49%, 39%, and 28%, respectively. Factors that had an effect in OS demonstrated by the multivariate regression analysis were: Tumor size, ER status, and nodal involvement (p < 0.001). Clinical outcomes in EBC in our experience are similar to those reported in international literature. The DFI and OS showed a statistically significant difference among the three groups. This group of pts continues to have a good prognosis as shown by the OS rate at 5, 10, 15, 20, and 25 years, although a high percentage of pts still to have recurrence and die from breast cancer after 5, 10, 15, 20, and 25 years of follow-up.     

Window of opportunity treatment in breast cancer

Window of opportunity therapies, which involve short‐term administration of systemic therapy between cancer diagnosis and surgery, have raised significant interest in recent years as a mean of assessing the sensitivity of a patient's cancer to therapy prior to surgery. There is now compelling evidence that in patients with early stage hormone‐receptor positive breast cancer, a 2‐week preoperative treatment with standard hormone therapies in a preoperative window period provides important prognostic information, which in turn helps to aid decision‐making regarding treatment options. Changes in short‐term biomarker endpoints such as cell proliferation measured by Ki‐67 can act as surrogate markers of long‐term outcomes. Paired tissues obtained pre‐ and post‐investigational treatment, without having to subject the patient to additional biopsies, can then be used to conduct translational research to investigate predictive biomarkers and pharmacodynamics. In this review, we will examine the utility and challenges of window of opportunities therapies in breast cancer in the current literature, and the current Australian and international trial landscape in this clinical space.     

Bone marrow micrometastases and adjuvant treatment of breast cancer

The immunohistochemical detection of epithelially derived cells in the bone marrow of patients with primary breast cancer has been shown to be associated with increased risk of distant relapse as well as higher rates of cancer-related death. Despite the correlation between bone marrow micrometastases and poor outcome in breast cancer patients, bone marrow status does not yet have an established role in patient management. In this prospective study, adjuvant therapy recommendations for 43 patients with stage I, II, or III breast cancer treated with lumpectomy or mastectomy, sentinel lymph node biopsy and/or axillary dissection, and intraoperative bone marrow aspiration were recorded. Recommendations were made by a multidisciplinary tumor board both blinded and unblinded to the results of the bone marrow aspiration. In our study, 10 of the 43 breast cancer patients were found to have bone marrow micrometastases. Four of these patients (40%) had axillary lymph node metastases. When blinded to the results of the bone marrow aspiration, the tumor board recommended adjuvant chemotherapy for these four node-positive patients, as well as two node-negative patients. When unblinded to the results of the bone marrow aspiration, the tumor board did not change its recommendations for any of these six patients. The remaining four node-negative, bone marrow-positive patients were not advised to have adjuvant chemotherapy by the tumor board when blinded to bone marrow status. However, once the tumor board was informed of the presence of bone marrow micrometastases, adjuvant chemotherapy was recommended for all of these patients. The results of this pilot study indicate that the presence of bone marrow micrometastases in breast cancer patients with stage I, II, or III disease does influence recommendations for adjuvant chemotherapy, particularly in patients with node-negative disease.     

The role of postoperative radiation therapy in stage I–III male breast cancer: A population-based study from the surveillance,epidemiology, and End Results database

BackgroundThis study aimed to investigate the role of postoperative radiation therapy in a large population-based cohort of patients with stage I–III male breast cancer (MaBC).MethodsPatients with stage I–III breast cancer treated with surgery were selected from the Surveillance, Epidemiology, and End Results cancer database from 2010 to 2015. Multivariate logistic regression identified the predictors of radiation therapy administration. Multivariate Cox regression model was used to evaluate the predictors of survival.ResultsWe identified 1321 patients. Age, stage, positive regional nodes, surgical procedure, and HER2 status were strong predictors of radiation therapy administration. There was no difference between patients who received radiation therapy and those who did not (P = 0.46); however, after propensity score matching, it was associated with improved OS (P = 0.04). In the multivariate analysis of the unmatched cohort, the factors associated with better OS were administration of radiation therapy and chemotherapy. In the subset analysis of the unmatched cohort, postoperative radiation therapy was associated with improved OS in men undergoing breast-conserving surgery (BCS), with four or more node-positive or larger primary tumours (T3/T4). Furthermore, we found no benefit of radiation therapy, regardless of the type of axillary surgery in mastectomy (MS). In older MaBC patients with T1-2N1 who underwent MS, radiation therapy showed no significant effects, regardless of chemotherapy.ConclusionPostoperative radiation therapy could improve the survival of MaBC patients undergoing BCS, with four or more node-positive or larger primary tumours. Moreover, it should be carefully considered in patients undergoing MS and older T1-2N1 patients.     

Progress in lung cancer: Non-oat cell (non-small cell lung cancer)

Lung cancer remains the greatest killing cancer in the United States with 149,000 new cases expected in 1987. The present expected mortality rate is 87 per cent. More women in the United States died of lung cancer than breast cancer in 1986. Asymptomatic, early and curable lung cancer in high risk individuals is usually found by routine chest X-ray. So-called Stage I lung cancer was reported to have a 83 per cent survival rate at three years by Martini and Beattie in 1977 and 70 per cent five year survival rate subsequently. When the more than 30,000 volunteer males were enrolled in the National Cancer Institute, national lung program for screening, 223 unsuspected lung cancers were found. 47 per cent were Stage I with a survival rate at five years of over 76 per cent. The PMI-Strang/Memorial Sloan Kettering Cancer Center study found 53 cancers in its first screen and 235 lung cancers over the next eight years of the study. Forty per cent were Stage I with a five year survival rate of 70 per cent. Sputum cytology as compared to chest X-ray was of little additional value. Studies (Martini) of N1 lung cancer was found to have a 49 per cent survival rate following resection. The N2 group of lung cancers where the mediastinal tumor was surgically removable and followed by external radiation therapy had a 27 per cent survival rate at five years. Those tumors with solitary brain metastases where the solitary brain metastasis could be resected and the primary tumor controlled, gave a 27 per cent survival rate at six years. The group of advanced N2 disease where the mediastinum could not be completely cleared were a serious group of cancers. A study of 100 patients treated from 1977 to 1980 with surgery plus internal radiotherapy followed by external radiotherapy had an overall 22 per cent survival rate for four to eight years with most of the deaths occurring because of metastases outside the chest. More recently chemotherapy has been used pre-operatively for those individuals with advanced lung cancer in the chest then followed by a combination of surgery, internal radiotherapy, external radiotherapy and more chemotherapy, if chemotherapy sensitive. This is the so-called multidisciplinary approach. In our present early studies it seems that those so treated who are chemotherapy sensitive have a 44 per cent, two year survival rate in a group of patients considered to have extremely poor prognosis.

Arguments for regional centralized treatment of stomach cancer. A statistical study of national results

An analysis was made of therapeutic results obtained from 6,220 cases of primary gastric carcinoma and from 1,308 cases of radical surgery, as listed in the 1976 National Cancer Record of the GDR. Results were examined relative to the number of radical operations per annum. Involved in the above treatment of gastric carcinoma were 237 surgical wards throughout the GDR. Numbers of radical operations were between one and four per annum in 56.1 per cent of all wards (Group I), between 5 and 19 in 40.5 per cent (Group II), and 20 or more in only 3.4 per cent (Group III). Radical removability accounted for 13.2 per cent of all cases in Group I, 28.2 per cent in Group II, and 38.5 per cent in Group III. Better therapeutic results relative to the number of radical operations per annum were reflected in the following absolute five-year survival rates: 3.4 per cent in Group I, 6.8 per cent in Group II, and 10.6 per cent in Group III. These findings are likely to support the advisability of regional centralisation of treatment for stomach carcinoma.
