Estimation of survival rates of breast cancer patients--a hospital-based study from Mumbai.

PURPOSE: To estimate the survival rates of breast cancer patients with reference to various factors like age, literacy status, residential status, T-stage and treatment. This is because there are very few studies reported from Indian subcontinent. METHODS: Survival rates were obtained by using the actuarial method and loss-adjusted survival rate method (LAR) for the above factors and the rates were compared. The present study carried out at the Tata Memorial Hospital (TMH), includes newly diagnosed (who were not treated elsewhere before attending TMH) primary breast cancer patients and having completed the initial treatment. RESULTS: The survival rates, actuarial survival and rates corrected for losses to follow-up (LAR) are presented. It showed that younger patients (<or=50 yrs) had a better 5-year survival ( 81%) than the older patients (> 50 years), with statistical significance ( p=0.024). There was no variation in survival with regard to the residential status but literate patients had a better ( non-significant) survival (77%) than their illiterate counterparts. T3-stage patients had the worst prognosis showing a 5-year survival of 60% (p=0.0002). Survival for those treated with surgery as the only modality and also in combination with other modalities did not show any remarkable differences except for the group that were treated with 'surgery in combination with chemotherapy'. The 5-year survival for those treated with surgery as the only modality was 83%. This study yielded useful information on breast cancer survival, especially in a situation with incomplete follow-up. The method applied (LAR) also clearly demonstrates the bias in estimates obtained by direct application of the standard actuarial method.

Squamous cell carcinoma of the maxillary sinus: a Tata Memorial Hospital experience.

BACKGROUND: The optimal treatment of maxillary sinus carcinoma remains to be defined and there is a paucity of Indian studies on the subject. AIMS: To present experience of management of squamous cell carcinoma of the maxillary sinus treated with curative intent at a single institution. SETTINGS AND DESIGN: Retrospective study of patients with squamous cell carcinoma of the maxillary sinus who presented between 1994 to 1999. MATERIALS AND METHODS: The records of 73 patients with squamous cell carcinoma of the maxillary sinus were analyzed. Sixty-two patients were evaluable. Forty patients (65%) were treated with surgery followed by postoperative radiotherapy, five patients (8%) were treated with radiotherapy alone, five patients (8%) were treated with surgery alone; 12 patients (19%) received chemotherapy. Statistical analysis used: Statistical analysis was done using Kaplan-Meier method. RESULTS: The majority of patients presented with locally advanced disease (52, 84%); nodal involvement was observed in five patients (8%). The most common site of recurrence was at the primary site, which was observed in 28 patients (45%) and regional failures occurred in 10 (16%). The 3 and 5-year overall survival was 38% and 35% and the disease free survival was 29% and 26% respectively. The 5-year overall survival after surgery and postoperative radiotherapy was 42%. CONCLUSIONS: The majority of patients present with advanced disease resulting in poor outcomes to conventional treatment modalities. Locoregional tumor progression remains a significant pattern of failure. New approaches such as neoadjuvant or concomitant chemoradiotherapy with aggressive surgery need to be considered and evaluated in prospective studies.
