Correlation of the Geriatric Assessment with Overall Survival in Older Patients with Cancer.

AIMS: Global guidelines recommend that all older patients with cancer receiving chemotherapy should undergo a geriatric assessment. However, utilisation of the geriatric assessment is often constrained by its time-intensive nature, which limits its adoption in settings with limited resources and high demand. There is a lack of evidence correlating the results of the geriatric assessment with survival from the Indian subcontinent. Therefore, the aims of the present study were to assess the impact of the geriatric assessment on survival in older Indian patients with cancer and to identify the factors associated with survival in these older patients. MATERIALS AND METHODS: This was an observational study, conducted in the geriatric oncology clinic of the Tata Memorial Hospital (Mumbai, India). Patients aged 60 years and older with cancer who underwent a geriatric assessment were enrolled. We assessed the non-oncological geriatric domains of function and falls, nutrition, comorbidities, cognition, psychology, social support and medications. Patients exhibiting impairment in two or more domains were classified as frail. RESULTS: Between June 2018 and January 2022, we enrolled 897 patients. The median age was 69 (interquartile range 65-73) years. The common malignancies were lung (40.5%), oesophagus (31.9%) and genitourinary (12.1%); 54.6% had metastatic disease. Based on the results of the geriatric assessment, 767 (85.4%) patients were frail. The estimated median overall survival in fit patients was 24.3 (95% confidence interval 18.2-not reached) months, compared with 11.2 (10.1-12.8) months in frail patients (hazard ratio 0.54; 95% confidence interval 0.41-0.72, P < 0.001). This difference in overall survival remained significant after adjusting for age, sex, primary tumour and metastatic status (hazard ratio 0.56; 95% confidence interval 0.41-0.74, P < 0.001). In the patients with a performance status of 0 or 1 (n = 454), 365 (80.4%) were frail; the median overall survival in the performance status 0-1 group was 33.0 months (95% confidence interval 24.31-not reached) in the fit group versus 14.4 months (95% confidence interval 12.25-18.73) in the frail patients (hazard ratio 0.50; 95% confidence interval 0.34-0.74, P = 0.001). In the multivariate analysis, the geriatric assessment domains that were predictive of survival were function (hazard ratio 0.68; 95% confidence interval 0.52-0.88; P = 0.003), nutrition (hazard ratio 0.64; 95% confidence interval 0.48-0.85, P = 0.002) and cognition (hazard ratio 0.67; 95% confidence interval 0.49-0.91, P = 0.011). DISCUSSION: The geriatric assessment is a powerful prognostic tool for survival among older Indian patients with cancer. The geriatric assessment is prognostic even in the cohort of patients thought to be the fittest, i.e. performance status 0 and 1. Our study re-emphasises the critical importance of the geriatric assessment in all older patients planned for cancer-directed therapy.

Validation of PREDICT Version 2.2 in a Retrospective Cohort of Indian Women With Operable Breast Cancer.

PURPOSE: Online prediction models that use known prognostic factors in breast cancer (BC) are routinely used to assist in decisions for adjuvant therapy. PREDICT Version 2.2 (P2.2) is one such online tool, which uses tumor size, lymph node involvement, grade, age, hormone receptor status, human epidermal growth factor receptor 2 (HER2) status, and Ki67. We performed an external validation in a retrospective cohort of patients treated at a tertiary center in India. METHODS: Women with operable BC between 2008 and 2016 with nonmetastatic, T1-T2 invasive, and HER2 receptor-negative BC and with available 5-year overall survival (OS) data were selected. Median predicted 5-year OS rates were used to calculate predicted events for the whole cohort and subgroups. The chi-square test was used to evaluate the goodness of fit of the tool. RESULTS: Of 11,760 cases registered between 2008 and 2016, 2,783 (23.66%) eligible patients with a median age of 50 (26-70) years and a median pT size of 2.5 (0.1-5) cm, 2,037 (73.19%) with grade 3 tumors, 1,172 (42.11%) with node-positive disease, 817 (29.35%) with triple-negative breast cancer, and 1,966 (70.64%) with HR-positive BC were included in the analysis. The observed 5-year OS and predicted 5-year OS in the whole cohort were 94.8% and 90.00%, respectively, with an absolute difference of 4.8% (95% CI, 3.417 to 6.198, P < .001). The observed 5-year OS and predicted 5-year OS were also different in various subgroups. CONCLUSION: PREDICT version 2.2 overestimated the number of deaths, with lower predicted 5-year OS compared with the observed value, in this retrospective Indian cohort. The reasons for this discrepancy could be differing biologic characteristics and possible selection bias in our cohort. We recommend a prospective validation of PREDICT in Indian patients and advocate caution in its use until such validation is achieved.

Accuracy of Intraoperative Frozen Section Analysis of Lymph Nodes in Women Undergoing Axillary Sampling for Treatment of Breast Cancer: Single Institution Audit.

BACKGROUND: Axillary lymph node (LN) positivity is an important prognostic factor in breast cancer. Almost 30% clinically node negative (cN0) early breast cancers have positive nodes on pathology, wherein an axillary dissection is done as a second stage surgery. Intra operative frozen section (FS) potentially avoids redo surgery. MATERIALS AND METHODS: We performed a retrospective audit for the false negative rate of intraoperative FS, from 2014 to 2018. All cN0 women undergoing upfront surgery, who underwent low axillary sampling (LAS) with FS were included. RESULTS: Of 22,854 breast cancer cases, 2230 underwent LAS, of which 877 were node positive. Intraoperative FS was negative in 1423/2230 (63.81%) cases, of which 71/1423 (4.98%) were false negative, and came positive on final histopathology report (HPR). These 71 women had a median of 5 nodes (mean 4.85) dissected on FS (range 1-12) with a median 1 (mean 1.3) node positive (range 1-6) on HPR. The sensitivity of FS was 91.89% (95% CI, 89.89-93.62), with a negative predictive value of 95.01% (95% CI, 93.84-95.97), accuracy of 96.73% (95% CI, 95.90-97.43) and false negative rate 4.98%. On logistic regression analysis, micrometastasis (Odds ratio (OR) 7.76, 95% CI, 3.49-17.25, P < .001) lobular histology (OR 2.50, 95% CI, 1.007-6.223, P = .04) and nodes dissected (OR 1.18, 95% CI, 1.07-1.30, P = .001) were associated with higher false negative FS, and extra nodal extension (OR 0.32, 95% CI, 0.18-0.57, P ≤ .001) with lower false negative FS. CONCLUSION: The high concordance between intraoperative FS and definitive histology, suggests it's routine use for Sentinel lymph node/LAS LN can help avoid a second surgery.

Will the proposed compensation guidelines for research-related injury spell the death knell for clinical research in India?

The Indian Council of Medical Research and the Central Drugs Standards Control Organization of the Directorate General of Health Services of the Ministry of Health and Family Welfare' draft guidelines for compensation of research-related injury have evoked strong responses from the clinical research community. All stakeholders, including academic researchers, teachers in medical colleges, the pharmaceutical industry and even members of Institutional Review Boards and Ethics Committees have expressed grave reservations about several clauses in the guidelines. Moreover, these two guidelines differ from each other in important areas, reiterating that more thought and discussion is necessary to refine the guidelines. We present an academic researcher's perspective of the guidelines and our views on how they will affect clinical research in the country. The paper covers the types of research-related injury that are entitled for compensation, controversies on whether injury resulting from standard care should be entitled for compensation, whether causality needs to be established as a prerequisite for eligibility for compensation and whether all forms of research should have mandatory provision for compensation. We also put forward the potential dangers of such recommendations, which could potentially be inducement for patients to participate in clinical research. Finally, we raise the philosophical issue of infringement of an individual's fundamental rights regarding what research he/she wishes to participate in. While these points are based on several formal and informal discussions with stakeholders from various fields of clinical research, the views expressed are the authors' own personal thoughts.

Pathological complete response in locally advanced breast cancer: determinants and predictive significance.

BACKGROUND: Neoadjuvant chemotherapy is now the standard approach for most large breast cancers including locally advanced cancers of the breast. The majority of patients respond satisfactorily to chemotherapy with effective downsizing of tumours to consider breast conservation surgery. Pathological complete response (pathCR) is known to be a strong predictor of good outcome; however, many factors are known to influence the extent of response to chemotherapy. It has been observed that smaller the tumour, better is the response achieved in contrast to larger and locally advanced tumours where only one-third may respond well enough to merit breast conservation. Various other clinical, biological and molecular factors are also being evaluated as effective predictors of chemosensitivity. Most of these are either not easily available for all patients in developing countries or are overtly expensive and not applicable for all patients. METHODS: We evaluated the clinical and pathological predictors of response to chemotherapy in 1402 women with locally advanced breast cancer. RESULTS: There was a higher rate of pathCR in smaller tumours, younger women and ER-negative as well as triple negative tumours. The presence of ductal carcinoma in situ (DCIS) and lymphatic and vascular invasion (LVI) were associated with lower pathCR. CONCLUSION: In the absence of ready availability of expensive molecular and genomic assays, clinical parameters and standard histopathological variables can also be useful indicators of response to neoadjuvant chemotherapy. Additionally, they can help identify those who could be eventually conserved or have a better outcome.

Transposition flap for the oncoplastic reconstruction of outer quadrant breast defects.

Plastic surgical principles are incorporated with breast conservation surgery (BCS) for cancer to improve aesthetic outcomes. In developing countries, average tumour size is larger at presentation resulting in larger resections often, including overlying skin. LD flap has been the workhorse of partial breast reconstruction. We present an easy and effective alternative to LD flap for carefully selected cases of outer quadrant breast tumours. We report 41 cases of local transposition flap from the lateral chest wall for oncoplastic restoration post BCS, performed between January 2016 and February 2020, at our institution. The median age was 49 years (28-63). Twenty-six patients underwent upfront surgery and 15 after neoadjuvant chemotherapy (NACT). The average pathological tumour size was 2.9 cm (median 2.7 and range 1.1-6) and 1.5 cm (median 1.8 and range 0-3.5) for upfront and post-NACT groups, respectively. The median volume of the resected specimen was 277.8 ml and 253.2 ml for upfront and post-NACT groups, respectively. Three patients (7.5%) had a microscopic positive margin requiring margin revision. Three (7.5%) patients had post-operative minor wound complications and were managed conservatively. At a median follow-up of 14 months (1-36), only 2/19 (10.5%) patients had clinical fat necrosis. Local transposition flap from the lateral chest wall based on dermal and subdermal plexus, carefully designed in selected patients, can be used effectively for the reconstruction of outer quadrant breast defects. It is easy to learn, offers good cosmetic outcome, avoids the morbidity and time of LD flap and saves LD flap for future use.

Can We Avoid Axillary Lymph Node Dissection (ALND) in Patients with 1-2 Positive Sentinel/Low Axillary Lymph Nodes (SLN/LAS+) in the Indian Setting?

The ACOSOG Z0011 study, heralded as a "practice changing" trial, suggested that women with T1-2 breast cancer with 1-2 SLN+, undergoing breast conservation therapy, need not be offered further ALND. However, whether these results are applicable to all women in the Indian setting, it remains debatable. A retrospective audit of all cN0 operated from 2013 to 2018 was conducted. We analyzed the percentage of additional LN positive (LN+) in the ALND group and compared it to the ACOZOG Z11 trial. Of the 2350 cN0 with EBC who underwent LAS, 687 (29%) had positive lymph nodes on final histopathology. Five hundred ninety-seven (86.9%) patients had 1-2 LN+, 40 (5.8%) patients had 3 LN+, and 50 (7.3%) had 4 or more nodes positive. Demographic features in the ACOSOG Z11 are different from those in our study, looking at ACOZOG Z11 versus our cohort-median pT 1.7 cm versus 3 cm, 45% micrometastasis versus 99.16% macrometastasis, and 28-30% grade 3 tumors versus 73.7%. In our cohort 31.82% of the 1-2 LN positive had additional LN+ on ALND. Keeping in mind the difference in clinicopathological features between our cohort and that of ACOZOG Z0011 and that 31.82% of women had additional LN+ on ALND, it may not be appropriate to apply the results of the ACOSOG Z0011 trial directly to our general population. Possibly, only a select subset of patients who match the trial population of the ACOSOG Z11 could be offered observation of the axilla and validated nomograms can be used to identify high-risk patients.

Trends in breast and cervical cancer in India under National Cancer Registry Programme: An Age-Period-Cohort analysis.

BACKGROUND: Trend analysis in cancer quantifies the incidence rate and explains the trend and pattern. Breast and cervical cancers are the two most common cancers among Indian women which contributed 39.4 % to the total cancer in India for the year 2020. This study aimed to report the time trends in cancer incidence of breast and cervical cancer using Age-Period-Cohort (APC) model from five Population Based Cancer Registries (PBCRs) in India for the period of 1985-2014. METHOD: Age-Period-Cohort model was fitted to five PBCRs of Bangalore, Chennai, Delhi, Bhopal and Barshi rural for breast and cervical cancer for 25-74 age-groups. The Estimated Annual Percent Change (EAPC) was calculated. Rate Ratio (RR) of cohort effects were estimated with a constraint of period slope to be zero (p = 0) since cohort has a stronger association with incidence than period. RESULT: A significant increase was noted in breast cancer in all PBCRs (EAPC, Range: Delhi, 1.2 % to Bangalore, 2.7 %) while significant decrease in cervical cancer (EAPC, Range: Bangalore -2.5 % to Chennai, -4.6 %) from all the PBCRs including Barshi rural during the period. RR estimates for breast cancer showed increasing trend whereas cervical cancer showed decreasing trend in successive birth cohorts across all five PBCRs. CONCLUSION: In both breast and cervical cancers, a significant age, cohort and period effect was noted in Bangalore, Chennai and Delhi. Despite period effect, the cohort effect was predominant and it may be attributed to the generational changes in risk factors among cancer breast and cervix.

Pregnancy associated breast cancer (PABC): Report from a gestational cancer registry from a tertiary cancer care centre, India.

BACKGROUND: Pregnancy associated breast cancer (PABC) is a rare entity and defined as breast cancer diagnosed during pregnancy or one-year post-partum. There is sparse data especially from low and middle-income countries (LMIC) and merits exploration. METHODS: The study (2013-2020) evaluated demographics, treatment patterns and outcomes of PABC. RESULTS: There were 104 patients, median age of 31 years; 43 (41%) had triple-negative disease, 31(29.8%) had hormone-receptor (HR) positive and HER2 negative, 14 (13.5%) had HER2-positive and HR negative and 16(15.4%) had triple positive disease. 101(97%) had IDC grade III tumors and 74% had delayed diagnosis. 72% presented with early stage (24, EBC) or locally advanced breast cancer (53, LABC) and received either neoadjuvant (n = 49) or adjuvant (n = 26) chemotherapy and surgery. Trastuzumab, tamoxifen, and radiotherapy were administered post-delivery. At a median follow up of 27 (IQR:19-35) months, the estimated 3-year event-free survival (EFS) for EBC and LABC was 82% (95% CI: 65.2-100) and 56% (95% CI: 42-75.6%) and for metastatic 24% (95% CI: 10.1%-58.5%) respectively. Of the 104 patients, 34 were diagnosed antepartum (AP) and 15 had termination, 2 had preterm and 16 had full-term deliveries(FTDs). Among postpartum cohort (n = 70), 2 had termination, 1 had preterm, 67 had FTDs. 83(including 17 from AP) children from both cohorts were experiencing normal milestones. CONCLUSION: Data from the first Indian PABC registry showed that the majority had delayed diagnosis and aggressive features(TNBC, higher grade). Treatment was feasible in majority and stage matched outcomes were comparable to non-PABCs.

Unique challenges and outcomes of young women with breast cancers from a tertiary care cancer centre in India.

BACKGROUND: Young (≤40 years) breast cancers (YBC) are uncommon, inadequately represented in trials and have unique concerns and merit studying. METHODS: The YBC treated with a curative intent between 2015 and 2016 at our institute were analysed. RESULTS: There were 1228 patients with a median age of 36 (12-40) years; 38 (3.1%) had Stage I, 455 (37.1%) - II, 692 (56.3%) -III, and remaining 43 (3.5%) Stage IV (oligo-metastatic) disease; 927 (75.5%) were node positive; 422 (34.4%) were Triple negatives (TNBC), 331 (27%) were HER-2 positive. There were 549 (48.2%) breast conservations and 591 (51.8%) mastectomies of which 62 (10.4%) underwent breast reconstruction. 1143 women received chemotherapy, 617 (53.9%) received as neoadjuvant and 142 (23.1%) had pathological complete response; 934 (81.9%) received adjuvant radiotherapy. At the median follow-up of 48 (0-131) months, 5-year overall and disease-free survival was 79.6% (76.8-82.5) and 59.1% (55.8-62.6). For stage I, II, III and IV, the 5-year overall-survival was 100%, 86.7% (82.8-90.6), 77.3% (73.4-81.2), 69.7% (52.5-86.9) and disease-free survival was 94% (85.9-100), 65.9% (60.3-71.5), 55% (50.5-59.5), and 29.6% (14-45.2) respectively. On multivariate analysis, TNBC and HER-2+ subgroups had poorer survival (p = 0.0035). 25 patients had BRCA mutations with a 5-year DFS of 65.1% (95% CI:43.6-86.6). Fertility preservation was administered in 104 (8.5%) patients; seven women conceived and 5 had live births. Significant postmenopausal symptoms were present in 153 (13%) patients. CONCLUSION: More than half of the YBC in India were diagnosed at an advanced stage with aggressive features leading to suboptimal outcomes. Awareness via national registry and early diagnosis is highly warranted. Menopausal symptoms and fertility issues are prevalent and demand special focus.

Low axillary sampling in clinically node-negative operable breast cancer.

BACKGROUND: Targeted sentinel node biopsy has been extensively validated. It has been incorporated into standard guidelines for axillary prediction in women with clinically node-negative operable breast cancer. However, the high cost of the gamma probe and the need for radiocolloid have limited its widespread acceptance in developing countries. We aimed to validate low axillary sampling as a reliable alternative method to sentinel node biopsy in a developing country. METHODS: An anatomically guided low axillary sampling removes the lower level I axillary fat with lymph nodes and the method was validated by completing axillary clearance in all women. RESULTS: Three hundred fifty-five women with clinically node-negative operable breast cancer underwent validation of low axillary sampling, with lymph nodes identified in all of them. The median number of nodes identified in low axillary sampling was 5 with overall node-positivity of 32.1% (114 of 355). Ten of these 114 patients were wrongly identified as node-negative by the sampled lymph nodes, i.e. a false-negative rate of 8.8%. Further exploratory analysis showed that 6-node low axillary sampling gave an excellent false-negative rate of 1.5% with 95% sensitivity, which was comparable with the highly targeted sentinel node biopsy technique. CONCLUSIONS: With an overall false-negative rate of 8.8% with 5-node low axillary sampling, and even better false-negative rate of 1.5% with 6-node low axillary sampling, axillary sampling is a low-cost technology, which is a reliable alternative to sentinel node biopsy for axillary nodal prediction in clinically node-negative breast cancer.

Does a less intensive surveillance protocol affect the survival of patients after treatment of a sarcoma of the limb? updated results of the randomized TOSS study.

AIMS: A single-centre prospective randomized trial was conducted to investigate whether a less intensive follow-up protocol would not be inferior to a conventional follow-up protocol, in terms of overall survival, in patients who have undergone surgery for sarcoma of the limb. Initial short-term results were published in 2014. PATIENTS AND METHODS: The primary objective was to show non-inferiority of a chest radiograph (CXR) group compared with a CT scan group, and of a less frequent (six-monthly) group than a more frequent (three-monthly) group, in two-by-two comparison. The primary outcome was overall survival and the secondary outcome was a recurrence-free survival. Five-year survival was compared between the CXR and CT scan groups and between the three-monthly and six-monthly groups. Of 500 patients who were enrolled, 476 were available for follow-up. Survival analyses were performed on a per-protocol basis (n = 412). RESULTS: The updated results recorded 12 (2.4%) local recurrences, 182 (36.8%) metastases, and 56 (11.3%) combined (local + metastases) recurrence at a median follow-up of 81 months (60 to 118). Of 68 local recurrences, 60 (88%) were identified by the patients themselves. The six-monthly regime (overall survival (OS) 54%, recurrence-free survival (RFS) 46%) did not lead to a worse survival and was not inferior to the three-monthly regime (OS 55%, RFS 47%) in terms of detecting recurrence. Although CT scans (OS 53%, RFS 54%) detected pulmonary metastasis earlier, it did not lead to a better survival compared with CXR (OS 56%, RFS 59%). CONCLUSION: The overall survival of patients who are treated for a sarcoma of the limb is not inferior to those followed up with a less intensive regimen than a more intensive protocol, in terms of frequency of visits and mode of imaging. CXR at six-monthly intervals and patient education about examination of the site of the surgery will detect most recurrences without deleterious effects on the eventual outcome.

Activation of phosphoinositide 3-kinase/Akt/mechanistic target of rapamycin pathway and response to everolimus in endocrine receptor-positive metastatic breast cancer - A retrospective pilot analysis and viewpoint.

INTRODUCTION: Biomarkers predictive of response to mechanistic target of rapamycin (mTOR) inhibitor, everolimus, in endocrine receptor (ER)-positive metastatic breast cancer (MBC) are a work in progress. We evaluated the feasibility of directly measuring mTOR activity and phosphatase and tensin homolog (PTEN) expression and correlating their expression with response and survival. MATERIALS AND METHODS: MBC patients who received everolimus with endocrine therapy (ET) after progression on an aromatase inhibitor and had adequate tissue preservation for estimation of mTOR activity and PTEN expression were selected for analysis from a prospectively maintained database. Progression-free survival (PFS) and overall survival (OS) were estimated by Kaplan-Meier method, and correlation between mTOR activity and PTEN expression with survival was done by log-rank test. RESULTS: Thirteen ER-positive MBC patients were available for analysis. PTEN expression was lost in 11/13 (84.6%) patients and retained in 2/13 patients (15.4%). mTOR activity was absent in four patients (30.7%), weak in six patients (46.1%), and moderate in 3 patients (23.2%). Median PFS for the entire population was 2.5 months while median OS was not reached. Patients with an absent mTOR activity showed a longer PFS (5 vs. 1.5 vs. 2 months) than those with weak and moderate activity, respectively (P = 0.043). There was no correlation between loss of PTEN expression and PFS. CONCLUSIONS: Measurement of direct mTOR activity in patients with MBC receiving everolimus/ET combination appears feasible. Absent mTOR activity may predict for longer PFS with everolimus-ET combination and requires further study.

Taxane Combination Chemotherapy in Breast Cancer: Experience from a Tertiary Cancer Centre in India.

AIMS: Docetaxel, Doxorubicin, Cyclophosphamide (TAC) is an intensive chemotherapy regimen; however, being highly myelosuppressive, its usage is limited in developing countries and hence merits exploration for feasibility and efficacy. MATERIALS AND METHODS: This was a retrospective audit of medical records of breast cancer patients receiving TAC chemotherapy) from 2004 to 2008. Demographic details, toxicity, and outcome analysis were carried out. RESULTS: A total of 133 patients (126 in [neo] adjuvant and 7 in metastatic setting) received TAC chemotherapy. The median age was 45 (21-67) years; 31% had coexisting diabetes and 12% hypertension. The delivered dose intensity was 94%. Discontinuation rate was 21/133 (15.8%) and the most common reason was hematological toxicity. There were 43 (32%) cases of febrile neutropenia and 2 (1.5%) Grade III thrombocytopenia with 3 (2%) toxic deaths. Grade III gastrointestinal toxicity (diarrhea) occurred in 35 (26%) and cardiac toxicity (congestive cardiac failure) in 2 (1.5%) patients. On univariate analysis, none of the variables (baseline serum albumin, hemoglobin, disease stage, or age) was found significant for chemotoxicity. At a median follow-up of 27 months (0.13-71.30 months), the estimated median disease-free survival (DFS) was 52 months in locally advanced group; however, the early breast cancer cohort has not reached to median DFS. CONCLUSIONS: TAC is an effective regimen but has significant toxicity despite the use of primary prophylactic Granulocyte Colony-Stimulating-Factor (G-GSF), including a small possibility of death. It can be considered "practically feasible" regimen in the adjuvant setting in carefully selected, fit patients.

Validation of EORTC quality-of-life questionnaire in Indian women with operable breast cancer.

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) module QLQ-C30 and the breast cancer-specific module BR-23 have been validated worldwide to assess the quality of life (QOL) in women with breast cancer. No such study has been published on Indian women using EORTC questionnaires. METHODS: QOL was assessed in relation to surgery, adjuvant chemotherapy, radiation therapy and hormone therapy in 299 Indian women with operable breast cancer (OBC) at the Breast Unit of Tata Memorial Hospital (TMH), Mumbai, from October 1998 to September 2001. The QLQ-C30 module was used to assess physical health, emotional, cognitive and social functioning, and the BR-23 module to assess breast cancer treatment-related symptoms. Assessment was done at 3 visits: visit 1 (after surgery); visit 2 (during adjuvant therapy) and visit 3 (on completion of adjuvant therapy). RESULTS: Of the 299 women at first visit, 274 (91.6%) completed the visit 2 questionnaire and 239 (80%) completed the visit 3 questionnaire. Only those women who filled the questionnaires at all 3 visits were included as 'valid visits' for analysis (193 of 299; 64.5%). The reliability and validity of the English and translated versions of the questionnaires were tested by Cronbach alpha (0.61-0.96) and item-scale correlation (0.63-0.93). Women with breast conservation treatment had a superior body image as compared to those with mastectomy (p <0.001). Physical, emotional and cognitive functions were not related to the type of surgery. Global QOL, physical, sexual and role functioning were found to deteriorate with chemotherapy (p < or = 0.01). Radiotherapy had only local adverse effects (p < 0.001 ), while hormone therapy had no adverse impact on QOL. CONCLUSION: QLQ-C30 and BR-23 questionnaires can be used reliably to assess QOL in Indian patients. The translated versions were found to be valid for further use in clinical trials on Indian women with breast cancer.

Cyclical tumour variations in premenopausal women with early breast cancer.

The hormonal milieu at the time of tumour excision may have a significant impact on survival in premenopausal patients with breast cancer, with those undergoing surgery between days 3 and 12 of the menstrual cycle having a worse prognosis. To investigate possible mechanisms which might explain this finding, histological features of tumours from 363 patients included in two studies from Guy's Hospital have been reviewed. Axillary nodal involvement occurred in 71/115 (62%) of patients whose primary tumour was excised between days 3 and 12 of the cycle, compared with 116/248 (47%) of patients undergoing surgery at other phases of the cycle (chi 2 = 7.04, P < 0.01). Vascular invasion was observed in 54/115 (47%) of primary tumours removed between days 3 and 12 and 82/248 (33%) of tumours removed at other times (chi 2 = 6.47, P < 0.02). Multivariate analysis of factors influencing survival indicated that both axillary nodal status and phase of the cycle were highly significant independent predictors of prognosis.

Serum progesterone at the time of surgery and survival in women with premenopausal operable breast cancer.

Serum progesterone and oestradiol levels have been measured in 210 premenopausal women with operable breast cancer on samples taken within 3 days of tumour excision. There was no relation between oestradiol level and time since last menstrual period, nor any effect of oestradiol value on prognosis. However, serum progesterone levels were related to the phase of the cycle as determined by time since last menstrual period. When divided on a basis of levels > 1.5 ng/ml (luteal phase) and < or = 1.5 ng/ml, it was found that there was no difference in survival between the two groups among 117 axillary node negative cases. However, in the 93 patients with positive axillary nodes, higher progesterone levels were associated with significantly better survival. Thus, serum progesterone levels at the time of surgery may affect the prognosis of premenopausal node positive patients with operable breast cancer.
