A retrospective analysis of epidemiology and treatment patterns for gastric cancer at a tertiary health care center in India
4086 Background: Gastric cancer is the second most common gastrointestinal cancer in our hospital based cancer registry. This retrospective analysis aims at studying the epidemiology and treatment patterns for gastric cancer at our hospital, which is a tertiary care cancer center for the state of Andhra Pradesh in south India. Methods: A retrospective analysis of the case records of 125 consecutive patients with gastric cancer who presented to our department between Jan 2004 and Dec 2005 were analysed. Data regarding epidemiology, stages at diagnosis and treatment plans were collected. Patients with early gastric cancer received 5FU based chemoradiation or chemotherapy only. Palliative chemotherapy included 5FU/cisplatin based regimens. Results: A total of 125 patients were analysed. The median age was 61years (range 18–82 years). 71% were males and 29% females. Being a tertiary care center, 92% were referred with a confirmed diagnosis on endoscopic biopsy. 30% were smokers, 11% consumed alcohol, 40% had both habits while 29% had neither. The most common part of the stomach involved was the antro-pyloric region (44%) followed by the body (30%), GE junction/cardia (20%) while 6% had diffuse involvement including linitis plastica. At diagnosis, 35% were early stage, 56% metastatic and 8% locally advanced tumors. 90% patients who had surgery for early stage disease had T2,3 tumors. One third had inadequate nodal staging.70% of patients who had curative resections underwent adjuvant chemoradiation and 30% had chemotherapy only. Of all patients with metastatic disease, 65% palliative chemotherapy while 45% opted for best supportive care. Conclusions: The distribution of tumors within the stomach is similar to Japanese data, which may reflect the common etiological factors like high salt diet. The fact that one third of patients had inadequate nodal dissection stresses the relevance of adjuvant chamoradiotherapy protocols. The high incidence of smoking as a contributory factor in the etiology reflects the need for aggressive anti tobacco legislation. The study reiterates the need for inexpensive and novel therapies for palliation of symptoms in patients with advanced disease and widens the scope for collaborative clinical trials.
