Risk factors effecting development of metachronous liver metastasis in rectal cancer patients after curative surgical resection. Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore experience.

OBJECTIVE: To determine risk factors affecting development of metachronous liver metastasis in rectal cancer patients after curative surgical resection. METHODS: The retrospective cohort study was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data of patients with histologically proven rectal carcinoma admitted to the department of surgical oncology from January 2005 to December 2015. Clinical data of all patients, including age, gender, clinical presentation, clinical and pathological tumour-nodes-metastasis classification, neoadjuvant chemo-radiotherapy, surgery, adjuvant chemotherapy, pre- and postoperative carcinoembryonic antigen levels, histopathological findings and tumour recurrence were analysed. SPSS 23 was used for data analysis.. RESULTS: Of the 434 patients, 26(6%) developed liver metastasis. Of them, 18(69%) were male and 16(61.5%) were aged below 50 years. On clinical staging, 2(7.7%) patients had stage II disease, 22(84.6%) had stage III, and 2(7.7%) patients had stage IV disease. At last follow-up, 2(7.7%) patients were alive without disease, 7(27%) had expired, while 17(65.4%) were alive with disease.. CONCLUSIONS: Tumour depth, lymph node metastasis, postoperative carcinoembryonic antigen levels, complete tumour response on histopathology were found to beresponsible for metachronous liver metastases in rectal cancer patients following curative resection.

Clinical profile, treatment and survival outcomes of peadiatric germ cell tumours: A Pakistani perspective.

Germ Cell Tumours (GCTs) are rare tumours. Generally 80% are benign and 20% malignant with a bimodal age distribution. The retrospective study was conducted at Shaukat Khanum Cancer Hospital, Lahore, Pakistan, and comprised all paediatric patients below 18 years of age who received treatment for histology-proven GCT from 2006 to 2014. Of the 207 patients, 98(42.3%) were males and 109(52.7%) were females. The most common GCT was yolk sac tumour in 90(43.5%) children followed by mixed GCT in 40(19.3%) and dysgerminoma in 34(16.4%). Gonads were most commonly involved in 165(79.7%) patients with metastasis in 24(11.6%) at presentation and recurrence in 26(12.5%) patients. Overall, 133(64.3%) patients are well and followed up at regular intervals and 55(26.5%) have been lost to follow-up with an expected overall 5-year median survival of 45%. Despite the distinct clinical profile of paediatric GCT, survival can be improved by early diagnosis, regimented treatment according to set guidelines, protocols and by improving follow-up.
