Clinical Practice Guidelines For The Management Of Colorectal Cancer, A Consensus Statement By The Society Of Surgeons® And Surgical Oncology Society Of Pakistan®.

A joint effort by the Society of Surgeons Pakistan and Society of Surgical Oncology Pakistan, these guidelines provide a framework for the practicing surgeons involved in care and management of patients with colorectal cancer. The guidelines take into account the issues related to our local circumstances and provide a minimum standard of care that must be given to these patients. The Guideline Committee had members from all disciplines, including surgery, surgical oncology, medical oncology and radiation oncology. The guidelines have attempted to simplify things to understand and follow for the practicing surgeons. With these guidelines we wish to eliminate disparities in treatment among institutions and prevent any under treatment of patients.

A retrospective study of endometrial stromal sarcoma: an institutional review.

This is a retrospective study conducted at Shaukat Khanum Memorial Cancer Hospital, Lahore, from January 1995 to April 2016, to determine the clinical presentations, pathological features, cancer free survival and rate of recurrence in patients with Endometrial Stromal Sarcoma (ESS). Data was collected from May to August 2017. A total of 31 patients with a mean age of 40.0±11.72 years were treated. Among them, 12 (38.7%) had stage I, 2 (6.4%) had stage II, 6 (19.3%) had stage III and 11 (35.5%) had stage IV ESS. All patients underwent surgical management as an initial treatment modality for ESS. Out of these 31 patients, 17 were under active surveillance, 4 had expired and 10 patients were lost to follow up. Eleven (65%) patients were disease free, recurrence was noted in 4 (23.5%) patients and 2 (12%) patients had persistent disease. Recurrence of disease was managed with surgical excision and multimodality treatment. Median duration of follow-up was 38.29 months. Endometrial stromal sarcoma (ESS) is a rare uterine tumour. Our patients were young and had lower rate of recurrence. Surgical management was the mainstay of treatment in patients with resectable disease while other options used included hormonal therapy, radio therapy or chemotherapy.

A Case Report on Rare Case of Pancreatic Metastasis from Primary Lung Adenocarcinoma: Treated Through a Non-surgical Approach.

Introduction: Most frequent sites of metastasis from lung cancer are the liver, brain and adrenal. Pancreas is an infrequent site of solitary metastasis from the lung primary with limited treatment options. There is insufficient data on the prognosis and optimal management of such cases. Case Description: We report a case of 44-year-old gentleman diagnosed with locally advanced lung adenocarcinoma Stage T4N3 who was treated radically with chemoradiation therapy, followed by a relapse of solitary pancreatic metastasis, which was treated with targeted therapy, erlotinib, due to the presence of epidermal growth factor receptor (EGFR) mutation. Practical Implications: This case reports an excellent radiological and symptomatic response in a patient who received erlotinib for advanced non-small-cell lung cancer (NSCLC). The use of EGFR-tyrosine kinase inhibitors has led to better prognosis and longer progression-free survival for patients with advanced NSCLC. However, the long-term survival of patients with metastatic NSCLC is limited.

Neoadjuvant Capecitabine and Oxaliplatin Before Concurrent Capecitabine and Radiation in Locally Advanced Rectal Cancers: Experience of a Cancer Hospital in Pakistan.

PURPOSE: To report the toxicity and pathologic response rates after adding neoadjuvant capecitabine and oxaliplatin (CAPOX) followed by concurrent radiation and capecitabine (CAPRT) and surgery in patients with locally advanced rectal cancer. MATERIALS AND METHODS: We retrospectively analyzed medical records of 301 patients between January 2007 and December 2014. Patients were treated with four cycles of neoadjuvant chemotherapy comprising CAPOX, followed by radiotherapy at doses of 45-54 Gy in 25-30 fractions with concurrent capecitabine. A response assessment scan was performed at 4-6 weeks postradiation followed by surgical evaluation at 6-8 weeks. Pathologic tumor and nodal response rates as well as circumferential resection margin were assessed on surgical specimens. RESULTS: The median age of the patients was 43 years (range, 16-78). Overall, 227 (75.4%) patients were able to complete four cycles of CAPOX. Neoadjuvant chemotherapy was well-tolerated with no serious adverse effects. The most common toxicity was diarrhea (grade 2, n = 108; 35.8%; grade 3, n = 57; 18.9%; grade 4, n = 25; 8.3%) followed by neuropathy (grade 2, n = 132; 43.8%; grade 3, n = 54; 17.9%) and oral mucositis (grade 2, n = 108; 35.8%; grade 3, n = 47; 15.6%; grade 4, n = 9; 2.99%). A total of 229 (76.1%) patients underwent surgery. Pathologic complete response was seen in 52 (22.7%; 95% CI, 13 to 28), whereas 200 (87.3%; 95% CI, 82 to 99) patients had a negative circumferential resection margin on pathology. CONCLUSION: Neoadjuvant chemotherapy with CAPOX before CAPRT and planned total mesorectal excision surgery result in good tumor regression and substantial pathologic complete response rates with acceptable toxicity. With growing interest in organ preservation in rectal cancer, the strategy of completing all chemotherapy and chemoradiotherapy before planned surgery offers a favorable paradigm. However, further randomized clinical trials are needed to support this evidence.

Long-Term Toxicity and Efficacy of Intensity-Modulated Radiation Therapy in Cervical Cancers: Experience of a Cancer Hospital in Pakistan.

PURPOSE: To report the chronic toxicity and disease outcomes attributable to intensity-modulated radiation therapy (IMRT) in patients with cervical cancer. METHODS AND MATERIALS: Between January 2014 and December 2018, a retrospective review of medical records of patients with cervical cancer who received radiation therapy with IMRT was performed. Disease and treatment-related details were documented. Follow-up notes were reviewed, and severity of late toxicities was recorded. Overall survival (OS) and disease-free survival (DFS) at 3 years were estimated. RESULTS: A total of 222 patients' records were reviewed. Mean age was 50.7 years. Median follow-up duration was 33 months (range, 2-70 months). The most common toxicity was vaginal stricture (grade 2, n = 59, 26.6%; grade 3, n = 4, 1.80%), followed by proctitis (grade 2, n = 24; 10.8%; grade 3, n = 7; 3.20%). Seven patients (grade 2, n = 5, 2.3%; grade 3, n = 2; 0.90%) developed cystitis, and only 5 (grade 2; 2.3%) were found to have colitis. None of the patients had grade 4 or grade 5 toxicities. There was a significant difference in late complications in patients with nodal disease or those who underwent prior surgery (P < .05). Three-year OS and DFS rates were 79.7% and 81.9%, respectively. Patients with tumor size > 5 cm and those with pelvic lymph node metastasis had poor survival rates (P < .05). CONCLUSION: IMRT is an effective and well-tolerated technique that should be considered in patients with lymph node disease and in postoperative patients. There is an inverse relationship between tumor size and nodal involvement with respect to OS and DFS.

Synchronous Primary Endometrial and Ovarian Cancers: Trends and Outcomes of the Rare Disease at a South Asian Tertiary Care Cancer Center.

Background and objective The incidence of synchronous primary endometrial and ovarian cancer is uncommon and poses a diagnostic challenge to the treating physician about their origin as either primary or metastasis. The purpose of this study was to evaluate the clinicopathological behavior, treatment modality-related outcomes, and prognosis related to primary endometrial and ovarian cancers at a tertiary care referral center in South Asia. Methods We retrospectively analyzed 30 patients with synchronous ovarian and endometrial cancers treated at Shaukat Khanum Memorial Cancer Hospital and Research Centre in Lahore, Pakistan from January 2005 to August 2017. Results The median age of the patients at the time of diagnosis was 51 years (range: 25-72 years). The common presenting symptoms were irregular uterine bleeding (30%), post-menopausal bleeding (26.7%), abdominal mass (16.7%), and abdominal pain (26.7%). Endometrial adenocarcinoma type was the most common histological variant found among the participants: 90% (n=27) of uterine and 56.7% (n=17) of ovarian cancers. All patients underwent surgical intervention. Among them, 25 patients received platinum-based adjuvant chemotherapy, four received neoadjuvant chemotherapy, and 18 received adjuvant radiotherapy. The early-stage group [International Federation of Gynecology and Obstetrics (FIGO) stage I and II] had a more favorable prognosis than the advanced stage group (FIGO stages III and IV). Conclusion Based on our findings, patients with synchronous primary endometrial and ovarian cancers have better overall survival rates than patients with single primary ovarian or endometrial cancers. Also, synchronous primary endometrial and ovarian cancer endometroid types have better overall survival than patients with non-endometrioid or mixed histologic types.
