Background/aim: Smokeless tobacco has been associated with oral cavity cancer for several decades. The incidence of oral cavity cancer is higher in some parts of the world especially South and South-East Asia including Pakistan. The aim of current study was to evaluate the risk of oral cavity cancer among smokeless tobacco users in our country. Materials and methods: A case-control study was conducted between November 2016 and September 2017. Patients diagnosed with oral cavity cancer receiving treatment were included as cases and the attendants of various cancer patients visiting the hospital during the study period were included in the study as controls. Odds ratios (OR) and 95% confidence intervals (CI) were calculated and all reported P-values were considered significant at < 0.05. Results: The crude OR for the "ever smokeless tobacco users" among cases and controls came out to be 4.98 (95%CI; 2.76-9.01). The OR for snuff users among cases and controls was 4.82 (95%CI; 2.37-9.80) and that for betel leaf users was 4.42 (95%CI; 1.66-11.91) after adjusting for smoking and age. Conclusion: Our study provided strong evidence for snuff and betel leaf to be independent risk factors for oral cavity cancer. [ABSTRACT FROM AUTHOR]

The Society of Surgeons of Pakistan and The Society of Surgical Oncology of Pakistan with factions from various major centres comprising of surgical oncology, medical and radiation oncology collaborated to reach consensus on breast cancer management guidelines and a framework of "good practice" minimum standards of care. The aim of the task force was to enhance treatment standards, which have a direct correlation with improving patient mortality and morbidity and long-term survival whilst taking into consideration economic limitations of access to leading centers of excellence as well as minimum expertise required in health care. These multidisciplinary guidelines, whilst not exhaustive, aim to provide an algorithm of care for breast cancer patients at tertiary care centres and district level hospitals to provide most appropriate treatment.

Diffuse large B-cell lymphoma (DLBCL) is the commonest non-Hodgkin lymphoma encountered by hematopathologists and oncologists. Management guidelines for DLBCL are developed and published by countries with high income and do not cater for practical challenges faced in resource-constrained settings. This report by a multidisciplinary panel of experts from Pakistan is on behalf of three major national cancer societies: Society of Medical Oncology Pakistan, Pakistan Society of Hematology, and Pakistan Society of Clinical Oncology. The aim is to develop a practical and standardized guideline for managing DLBCL in Pakistan, keeping in view local challenges, which are similar across most of the low- and middle-income countries across the globe. Modified Delphi methodology was used to develop consensus guidelines. Guidelines questions were drafted, and meetings were convened by a steering committee to develop initial recommendations on the basis of local challenges and review of the literature. A consensus panel reviewed the initial draft recommendations and rated the guidelines on a five-point Likert scale; recommendations achieving more than 75% consensus were accepted. Resource grouping initially suggested by Breast Health Global Initiative was applied for resource stratification into basic, limited, and enhanced resource settings. The panel generated consensus ratings for 35 questions of interest and concluded that diagnosis and treatment recommendations in resource-constrained settings need to be based on available resources and management expertise., Competing Interests: Munira MoosajeeTravel, Accommodations, Expenses: Roche Kamran RashidHonoraria: Roche/GenentechSpeakers' Bureau: Roche/Genentech, Lilly MedicalTravel, Accommodations, Expenses: Roche Usman AhmadHonoraria: RocheTravel, Accommodations, Expenses: RocheNo other potential conflicts of interest were reported.

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.

Objectives: To determine the frequency and grades of acute side effects with three-dimensional brachytherapy in carcinoma cervix using RTOG/EORTC acute radiation morbidity scoring criteria., Study Design: Descriptive study., Place and Duration of Study: Department of Radiotherapy, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, Pakistan from July 2016 to September 2017., Methodology: A total of 55 histologically proven patients of squamous cell carcinoma of the cervix, aged between 16-70 years, were included. Patients with previous radiotherapy in pelvic area, inflammatory bowel diseases and known diabetics, were excluded. All patients were given a radiation dose of 7 Gray in 4 insertions through 3-dimensional conformal brachytherapy planning. Acute vaginal, gastrointestinal, and genitor-urinary side effects of brachytherapy were assessed., Results: Mean age of the patient population was 47.09 ±13.10 years (Range: 21-68). Mean time to presentation was 5.65 ±2.32 months and mean tumor size was 3.67 ±1.47 cm. Majority, i.e. 18 (32.7%) patient presented in stage III. Most of the patients, 26 (47.3%), had ECOG-2 performance status. Grade-1 genitourinary toxicity was significantly high (p <0.001). In lower gastrointestinal toxicity, Grade-1 was the highest being 54.5%. Conversely, vaginal toxicities of grade-2 and 3 were most commonly seen. Stratification of acute side effectswith respect toage, stage and tumor size revealed no significant association except in mucosal membrane toxicity, which was affected by tumor size (p = 0.004)., Conclusion: Three-dimensional brachytherapy in carcinoma cervix is a safe and tolerable procedure with minimal acute side effects. Key Words: Cervical cancer, Brachytherapy, Acute toxicities, Computed tomography.

Objective: To study the cancer incidence rates in Lahore, which has an estimated annual population count of 10.3 million., Study Design: Cross-sectional study., Place and Duration of Study: Data on new cancer cases diagnosed between 2010 and 2015, among the residents of Lahore district, Pakistan, was reviewed retrospectively in 2015-2017., Methodology: Nineteen collaborating centres of the population-based Punjab Cancer Registry (PCR), representing both the government and private sectors, reported their cases to the coordinating office located within the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC). The age-standardised incidence rates (ASIR) per 100,000 population, over a six-year period, were computed. Sixteen 5-year age groups were created beginning from 0-4 to 70-74 years, followed by 75+ years. Graphs on the five-year age-specific incidence rates by gender, were also generated., Results: Between 2010 and 2015, 33,028 new malignancies were recorded in Lahore, with the crude average annual incidence rate being 53.1. In adults, the highest ASIRs were noted for cancers of the breast (77.3) among females and of prostate (11.4) in men. Age-specific incidence rates for female breast cancer showed an upward trend at the age of 20 years, reaching a figure of 160 at the age of 55 years. Among males, the rates for prostate cancer started to increase at the age of 55 years and reached a peak of 93 at 75 years., Conclusion: These results warrant expanding cancer registration in the region and sharing statistics with policy-makers to establish hospitals accordingly to manage cancer, along with exploring various risk factors within the population.

Objective: To find the epidemiology and risk factors of sinonasal tumors and treatment outcomes in squamous cell carcinoma., Study Design: An observational study., Place and Duration of Study: The Institute of Nuclear Medicine and Oncology Lahore (INMOL), Lahore, from May 2016 to March 2017., Methodology: All histopathologically proven cases of paranasal sinuses and nasal cavity were selected from the hospital record for epidemiological analysis. Survival outcomes of patients with squamous cell histopathology were determined, which is commonly occurring type. Relevant information was obtained from patient record and telephone communication. The data were analysed using SPSS V.20., Results: Sinonasal malignancies are rare, making (n=81) 0.2% of all registered tumors; out of which, 46 (56.7%) had squamous cell histology. Median age was 50.0 years (IQR: 60.7-40.0) with male predominance (1.7:1). Most of patients presented at advanced stage, T3/ T4 in more than two-thirds of cases, and associated with nodal metastasis in 43.5% of squamous cell carcinoma. In patients with squamous cell histology, median disease-free survival was 19.00 months (SE: 1.65, 95% CI, 15.75 - 22.25), median overall survival remained 34.00 months (SE: 1.84, 95% CI, 30.00 - 38.00). Nodal status had significant effect (p<0.001) on survival. Radiotherapy had significant effect on improved survival (p=0.001) and distant metastasis remained negative prognostic factor (p=0.001). Disease stage was also significantly associated with overall survival (Log Rank 0.014). Tumour size, surgery, chemotherapy, and chemoradiotherapy were not significantly associated with survival. Cumulative survival at 1, 2, and 3 years was 87%, 48% and 29%, respectively., Conclusion: Sinonasal malignancies are rare, advanced stage is common, and radiotherapy improves overall survival.

Objective: To evaluate the efficacy of concurrent chemoradiation in patients with locally advanced inoperable squamous cell carcinoma of oral cavity in terms of local control and toxicity., Study Design: Case series., Place and Duration of Study: Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from January 2008 to December 2013., Methodology: Sixty-nine patients with locally advanced inoperable oral cavity cancer, registered in INMOL hospital from January 2008 to December 2013 who fulfilled a pre-defined eligibility criteria, were enrolled in the study. Concurrent chemoradiation protocol consisted of conventional fractionation delivering 70 Gy with weekly Cisplatin (50 mg/m2) during the course of radiation. Tumor response was calculated by RECISTcriteria version 1.1 along with the median overall survival and disease-free survival. Acute treatment related toxicities were graded as (G)., Results: Thirty-six (52.17%) patients showed complete response; while 19 (27.54%), 8 (11.59%) and 6 (8.7%) were observed with partial response, stable and progressive disease, respectively. Treatment response was significant (p<0.001) in terms of responders vs. non responders to treatment. Median overall survival was 18.00 months; whereas, median disease-free survival remained 14.00 months. Main toxicities included mucositis (G3 and G4, 71%), xerostomia (G2 and G3, 82.5%), vomiting (G3 and G4, 51%), myelosuppression (G3 and G4, 26.2%), dermatitis (G3 and G4, 49.2%), and fatigue (G3 and G4, 57.9%)., Conclusion: Platinum based CCR Tremained effective for inoperable oral cancer patients.

Single nucleotide polymorphisms (SNPs) lead to genetic differences in breast cancer (BC) susceptibility among women from different ethnicities. The present study aimed at investigating the involvement of SNPs of three genes, including fibroblast growth factor receptor 2 (FGFR2), trinucleotide-repeat-containing 9 (TNRC9) and mitogen-activated protein kinase kinase kinase 1 (MAP3K1), as risk factors for the development of BC. A case‑control study (90‑100 cases; 90‑100 controls) was performed to evaluate five genetic variants of three genes, including FGFR2 (SNPs: rs1219648, rs2981582), TNRC9 (SNPs: rs8051542, rs3803662) and MAP3K1 (SNP: rs889312) as BC risk factors in Pakistani women. Significant associations were observed between BC risk and two SNPs of FGFR2 [rs2981582 (P=0.005), rs1219648 (P=9.08e‑006)] and one SNP of TNRC9 [rs3803662) (P=0.012)] in Pakistani women. On examining the different interactions of these SNPs with various clinicopathological characteristics, all three associated genetic variants, rs2981582 rs1219648 and rs3803662, exhibited a greater predisposition to sporadic, in comparison to familial, BC. Furthermore, there was an increased effect of BC risk between haplotype combinations of the two SNPs of FGFR2 (rs2981582 and rs1219648) in Pakistani women. The results of the present study suggest that variants of FGFR2 and TNRC9 may contribute to the genetic susceptibility of BC in Pakistani women.

Background: The Pakistan Atomic Energy Commission Cancer Registry (PAECCR) program has made availability of a common cancer incidence database possible in Pakistan. The cancer incidence data from nuclear medicine and oncology institutes were gathered and presented., Materials and Methods: The cancer incidence data for the last 30 years (1984-2014) are included to describe a data set of male and female patients. The data analysis concerning occurrence, trends of common cancers in male and female patients, stage-wise distribution, and mortality/follow-up cases is also incorporated for the last 10 years (2004-2014)., Results: The total population of provincial capital Lahore is 9,800,000. The total number of cancer cases was 80,390 (males 32,156, females 48,134). The crude incidence rates in PAECCR areas were 580.8/105 during 2010 to 885.4/105 in 2014 (males 354.1/105, females 530.1/105). The cancer incidence rates for head and neck (15.70%), brain tumors (10.5%), and non-Hodgkin lymphoma (NHL, 9.53%) were found to be the highest in male patients, whereas breast cancer (46.7%), ovary tumors (6.80%), and cervix (6.31%) cancer incidence rates were observed to be the most common in female patients. The age range distribution of diagnosed and treated patients in conjunction with the percentage contribution of cancer patients from 15 different cities of Punjab province treated at the Institute of Nuclear Medicine and Oncology, Lahore are also included. Leukemia was found to be the most common cancer for the age group of 1-12 years. It has been identified that the maximum number of diagnosed cases were found in the age range of 51-60 years for males and 41-50 years for female cancer patients., Conclusions: Overall cancer incidence of the thirty years demonstrated that head and neck and breast cancers in males and in females respectively are the most common cancers in Punjab province in Pakistan, at rates almost the highest in Asia, requiring especial attention. The incidence of brain, NHL, and prostate cancers among males and ovarian and cervix cancers among females have increased rapidly. These data from a major population of Punjab province should be helpful for implementation of appropriate planning, prevention and cancer control measures and for determination of risk factors within the country.

Objective: To summarize the data and look into the various treatments offered to cervical cancer patients at Institute of Nuclear Medicine and Oncology (INMOL) to highlight the most likely causes of treatment failure., Methods: In this retrospective study, case files of all patients presenting with invasive carcinoma of uterine cervix during 1993-2002 were studied in respect to personal profile, disease related risk factors, pathological characteristics, treatment administered and outcome in the form of tumour response and survival., Results: Early age at marriage, multiple marriages of self or spouse, multiparty, prolonged use of contraceptives and smoking were some of the risk factors for cervical cancer in this group of patients. Out of 618 patients presenting with invasive cervical cancer, 65% presented in advanced stages II and III. Apart from advanced stage at presentation, anaemia, poor nutrition, and ignorance about self-hygiene and lack of follow-up were main causes of treatment failure. Outcome of treatment was improved when chemotherapy was added to radiation., Conclusion: Advanced stage at diagnosis and lack of follow-up were main causes of treatment failure. Implementation of screening programs on national level for early detection is therefore recommended.
