Cancer incidence in Khyber Pakhtunkhwa, Pakistan, 2020.

BACKGROUND: To present the population-based cancer statistics for Khyber Pakhtunkhwa (KP), Pakistan, an incidence study was conducted at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) in Lahore, Pakistan, in 2023. METHODS: Records from various centres on new cancers diagnosed among residents of KP between January and December 2020 were gathered. Both active and passive methods of data collection were applied, and the information was saved in a central repository at SKMCH&RC. The incidence rates were computed by age group and sex and presented per 100,000 population. RESULTS: Among children (0-14 years), the Age-Standardised Incidence Rate (ASIR) was 4.0 in girls and 6.1 in boys, and haematologic malignancies were more prevalent; in adolescents (15-19 years), the ASIR was 7.7 in females, 9.4 in males, and bone tumours, haematologic malignancies, and neurological cancers were prominent; in adult females (> / = 20 years), the ASIR was 84.9, and cancers of the breast, digestive system, and reproductive organs were predominant; and adult males, the ASIR was 73.0, and cancers of the gastrointestinal tract, lip/oral cavity/pharynx, prostate, and Non-Hodgkin Lymphoma (NHL) were common. CONCLUSIONS: It is crucial to investigate the aetiology of these diseases at the community level because dietary elements, infectious diseases, and tobacco use all appear to be significant contributors. Prospective studies could play a key role in highlighting the factors linked to these diseases. Therefore, cancer registration must continue in conjunction with the exploration of risk factors.

Cardiovascular disease risk factors in Pakistani population with newly diagnosed Type 2 diabetes mellitus: A cross-sectional study of selected family practitioner clinics in four provinces of Pakistan (CardiP Study).

OBJECTIVE: To explore cardiovascular risk factors in people with newly-diagnosed type 2 diabetes mellitus. METHODS: The cross-sectional, prospective, multicentre, study was conducted from June 2014 till July 2015 at family practice clinics in 27 cities across Pakistan, and comprised individuals aged 30-50 years diagnosed with type 2 diabetes mellitus within the preceding six months. Laboratory investigations were conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, and Aga Khan University Hospital, Karachi. The 10-year absolute risk of fatal or non-fatal coronary heart disease and stroke was calculated using the United Kingdom Prospective Diabetes Study Risk Engine version 2.0. Data were analysed using SPSS 19. RESULTS: Out of 888 subjects, 362(40.8%) were women and 526(59.2%) were men. The overall mean presenting age was 42.4}5.8 years. After stratification by age, those ≥40 years were significantly associated with higher glycated haemoglobin (p=0.02) and those ≤39 years were associated with higher levels of very low density lipoprotein (p=0.001) and triglyceride (p=0.006). The mean risk estimate for CHD was 9.7% (95% Confidence Interval (CI) 9.0- 10.1)), for fatal CHD 4.4% (95% CI 4.0-4.6), for stroke 1.5% (95% CI 1.2-1.7), and for fatal stroke 0.25% (95% CI 0.24- 0.26). CONCLUSIONS: There is a need for screening cardiovascular risk factors even in younger age groups of newlydiagnosed diabetes.

Characteristics and outcomes of patients with multiple myeloma : Data from a developing country.

Background: Multiple myeloma (MM) is a plasma cell disorder characterized by presence of monoclonal protein in serum or urine or both, increased bone marrow plasma cells, osteolytic lesion, hypercalcemia, and anemia. Several combination regimens are commonly recommended for treatment of multiple myeloma. The present study aimed at determining the characteristics and outcomes of patients with multiple myeloma treated at our centre. Methods: During July 2012 and December 2015, all patients with proven diagnosis of MM were included in this study. Data were collected from hospital information system. The characteristics and outcomes of all patients were analyzed. Progression- free survival and overall survival of patients were also estimated. Kaplan-Meier curves and Log-rank test were applied and SPSS Version19 was used for data analysis. Results: A total of 82 patients, with the median age of 51 years (Range: 23-64 yrs.) were available for final analysis. The number of patients with IgG and IgA type was 48 (58.5%) and 15(18.3%), respectively. There were 7 (8.5%) patients with non-secretory type. Most of the patients (n= 59; 71.9%) were treated with CTD regimen and 13 (15.8%) received bortezomib-based treatment. The median progression-free survival time was 30 months, and overall survival time was 48 months. The cumulative probability of survival at 36 months was 85%. Conclusion: Based on our results, the onset of multiple myeloma occurs in relatively younger age groups. A small number of patients received bortezomib due to cost issues. PFS and OS in our study were comparable with published literature.

Efficacy And Toxicity Of Carboplatin/Paclitaxel Based Chemoradiation For Localized Oesophageal Cancer.

BACKGROUND: The management of Oesophageal and Gastroesophageal junction cancers is challenging. Multimodality therapy with carboplatin/paclitaxel based chemoradiation (CRT) and surgery shows improved efficacy. In this study, we wanted to establish the efficacy and safety of CRT for neoadjuvant and radical treatment of localized oesophageal cancer. METHODS: Patients with oesophageal cancer, registered between September 2013 and October 2014 were reviewed retrospectively. Toxicity and efficacy analysis in the form of radiological response rate, R0 resection rate, Progression free survival (PFS) and overall survival (OS) was performed on 102 patients who received radical carbo/pacli induction chemotherapy followed by CRT. Impact of Surgery was seen on PFS and OS. RESULTS: Males and females were 71 (51.1%) and 68 (48.9%) respectively, with squamous cell carcinoma being the predominant histology (92%). Majority of patient belonged to T3/4 and N1 stage. Grade III/IV thrombocytopenia, neutropenia, anaemia, febrile neutropenia requiring hospitalisation, non-hematologic toxicities were noted in 13 (12.8%), 18 (17.7%), 18 (17.7%), 1 (1%), 1 (1%), patients respectively. Complete Radiological response, partial response, Stable disease, progressive disease was seen in 6 (5.9%), 51 (50%), 23 (22.5%) 8 (8.7%), respectively. Resection was done in 29 (28.4%). Complete and partial pathological response were seen 19 (65.5%), 10 (34.4%), respectively. PFS at 40 and 80 weeks was 90%, 73%, respectively and OS at 80 weeks was 86%. PFS at 40 and 80 weeks was 100% and 90.5%, respectively with resection, while it was 86% and 65%, without resection (P value 0.015). OS at 40 and 80 weeks was 100% (both) with resection, while it was 96% and 79.5% weeks without resection. (p-value 0.034). CONCLUSIONS: Carbo/pacli based CRT is effective with acceptable toxicity profile in treating localised oesophageal cancer as both as Radical CRT and as a part of multimodality therapy. For definitive results, long term follow up and prospective analysis are required.

Characteristics And Outcome Of Patients With Diffuse Large B Cell Lymphoma-Treated With Chemotherapy Or Chemo-Immunotherapy.

BACKROUND: Diffuse large-B-cell lymphoma, is the most common subtype of Non-Hodgkin lymphoma. Aim of this study was to look at the characteristics and outcome of DLBCL patients who were treated with chemotherapy or chemotherapy plus rituximab at our institution. METHODS: Data of 750 patients, who got registered at our institute between 2007 and 2014, was reviewed retrospectively. After appropriate exclusions, 337 were included. Disease free survival (DFS) and overall survival (OS) were compared between patients who received rituximab plus CHOP (Cyclophosphamide, Doxorubicine, Vincristine, Prednisolon) (R-Ch) and standard chemotherapy- CHOP (S-Ch). RESULTS: Males and females were 216 (64%) and 121 (36%) respectively, with median age 38 years (Range 18-80 yrs.). R-Ch and S.Ch was received by 129(38.3%) and 197(58.4%) patients, respectively. Complete remission (CR) was achieved by 81 (62.8%) vs. 105 (53.3%) patients in R-Ch vs. S-Ch cohorts, respectively. In subset analysis CR was seen in 34 (63.0%) and 45 (58.4%) (p=0.01) in R-Ch/XRT and S-Ch/XRT, respectively. At three years, DFS was 85.3% vs. 74% (p=0.04) and OS was 82.2% vs. 72.6% (p=0.02) in R-Ch and S-Ch cohorts respectively. Deaths observed were 9 Vs.13 in R-Ch/XRT and S-Ch/XRT, respectively. CONCLUSIONS: Based on our study, onset of DLBCL is at younger age in our population with male predominance. Addition of rituximab to CHOP resulted in better DFS and OS in patients with DLBCL. In developing countries, due to cost, large number of patients do not have access to rituximab. Efforts should be made to reduce the price of targeted therapies so that more and more patients are benefitted from these newer agents.

Outcomes of first line chemotherapy in patients with chronic lymphocytic leukemia.

OBJECTIVE: Chronic lymphocytic leukemia (CLL) is a heterogeneous disease in terms of survival with and without treatment. Many chemo and immunotherapeutic agents are available to treat this indolent disease. Aim of this study was to determine the outcomes of patients with chronic lymphocytic leukemia treated with different available chemotherapeutic regimens. METHODS: All patients with diagnosis of CLL from 2008 to 2013 were included. Data were collected from hospital information system. Objective response rate (ORR) in terms of complete or partial response (CR, PR), stable or progressive disease (SD, PD), overall survival (OS), and progression free survival (PFS) were calculated. RESULTS: Fifty seven patients were included; 42 (74%) male and 15 (26%) were female. Patients with Binet stage A 10 (18%); B 20 (35%) and C were 27(47%). Median age was 50.9 years. Forty six (80%) were treated and 11(20%) remained on watch and wait. Treatment indications were B symptoms 14 (30%), symptomatic nodal disease 18(39%), thrombocytopenia 4(9%), anemia 7(15%) and doubling of lymphocyte count 3 (7%). Chemotherapy regimens used were FC in 38 (83%), FCR 5(11%), chlorambucil 2(4%) and CVP in 1(2%) patient. Twenty two (56%) patients had CR, 13(33%) PR, 3(7.6 %) SD, and 1(2.5%) had PD. ORR was 89%. Median PFS was 23.1 months and median 3 years OS was 55%. CONCLUSION: Majority of patients was in a relatively younger age group and presented with advanced stage disease requiring treatment. Small number of patients received rituximab due to cost. PFS and OS are comparable with published literature.

Chemotherapy alone or combined chemotherapy and involved field radiotherapy in favorable risk early-stage classical Hodgkin lymphoma-a 10 years experience.

OBJECTIVE: To determine the outcome of patients with early-stage (stage I-II) favorable risk classical Hodgkin lymphoma treated with chemotherapy alone or combined modality treatment (CMT) utilizing chemotherapy and involved field radiotherapy. METHODS: This retrospective study was done at Department of Medical oncology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore, Pakistan from January 2004 to December 2013. RESULTS: There were 101 patients, with male predominance (71.3%). Mean age was 34 years. Sixty three (62.4%) patients received CMT and 38 (37.6%) patients had chemotherapy alone. Ninety eight percent patients had ABVD chemotherapy. Dose of radiotherapy ranged from 20 to 36 gray. Difference between baseline characteristics and major toxicities among the two groups was insignificant. Patients treated with CMT had better overall survival compared to chemotherapy alone: 100% versus 91% at five years and 96% versus 81% at 10 years, respectively (p=0.03). Progression free survival was also better with CMT against chemotherapy alone at five years (98% versus 81%) and 10 years (82% versus 71%) (p=0.01). CONCLUSION: Favorable risk classical Hodgkin lymphoma patients had better overall survival and progression free survival when treated with CMT against chemotherapy alone.

CANCERS AMONG CHILDREN AND ADOLESCENTS AT A CANCER HOSPITAL IN PAKISTAN.

BACKGROUND: The Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH & RC), is a tertiary care cancer centre, providing the best facilities in cancer diagnosis and treatment in the region. A record of the registered patients is being maintained in the hospital-based registry and the results are posted on its official website on a regular basis. METHODS: This is an epidemiologic review of cancer patients 0-19 years of age, reporting cancers recorded at SKMCH & RC) Lahore, Pakistan, from January 1, 2011 - December 31, 2012, in patients aged less than or equal to 19-years, belonging to Lahore district. It includes: i) those who had come to the Hospital laboratory for diagnosis only; ii) those who were diagnosed and registered for treatment at the Hospital; and iii) those who were not accepted for registration (regardless of the centre of diagnosis), as per Hospital policy, and subsequently went to other centres for treatment. The results were summarized by sex, 5-year age-group (0-4, 5-9, 10-14, and 15-19), and the International Classification of Childhood Cancers' (ICCC) diagnostic group. The annual Age-Standardized Incidence Rates (ASIR) were computed through the Segi World Standard (1960), per 100,000 population. RESULTS: New cancer cases: 669. ASIRs for common malignancies: among males-leukaemia and myelo-proliferative/dysplastic disorders 2.1, lymphoma and reticuloendothelial neoplasms 1.8, CNS and miscellaneous intracranial/intraspinal tumours 1.1; among females-leukaemia and myelo-proliferative/dysplastic disorders 1.9, CNS and miscellaneous intracranial/intraspinal 0.8, and malignant bone tumours 0.6. CONCLUSION: The rates are low compared to the rates reported in the West. However, it has been estimated that over 80% of the paediatric cancer cases, diagnosed among Lahore residents, are being recorded by this institution alone. Accordingly, reviewing the statistics on a regular basis can be very important in evaluating trends in childhood cancers in Lahore and implementing cancer control programs in the region.

FACTORS ASSOCIATED WITH INCREASED RED BLOOD CELLS TRANSFUSION REQUIREMENTS IN PATIENTS WITH HODGKIN AND NON-HODGKIN LYMPHOMA.

BACKGROUND: Anaemia is a common feature of lympho-proliferative disorders and is an important cause of poor quality of life in these patients. When indicated, packed red blood cells (PRBC) units are transfused to treat anaemia. Objective of this study was to identify risk factors associated with PRBC transfusions in lymphoma patients. METHODS: This was a retrospective study done on Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL) patients who had PRBC transfusions during chemotherapy. Information regarding gender, type of lymphoma, stage, baseline haemoglobin, marrow involvement and total number of PRBC units transfused was collected. RESULTS: A total of 481 patients with diagnosis of HL and NHL were registered during one year period. Out of these, 108 (22.4%) had PRBC transfusions during treatment. HL and NHL patients were 30 (27.8%) and 78 (72.2%) respectively. NHL patients were older than HL (37 vs. 32 years), (p=0.03). HL patients had lower mean haemoglobin 9.3 +/- 2.56 g/dl as compared to NHL 11.33 +/- 2.42 g/dl, (p<0.05). There was significant difference in number of PRBC units transfused based on lymphoma type (NHL 6.74 +/- 5.69 vs. HL 3.97 +/- 3.0 units, p<0.05). Bone marrow involvement resulted in increased transfusion requirements (7.84 +/- 4.36 vs. 5.26 +/- 5.49 units, p<0.05) while stage of disease didn't affected significantly (I/II--4.88 +/- 4.85 and III/IV 6.30 +/- 5.33 units p=0.2). CONCLUSION: A significant number of lymphoma patients need PRBC transfusions during chemotherapy. NHL patients and bone marrow involvement makes patients at higher risk for transfusions. In places, where blood bank support is not adequate, patients should be informed right from beginning to arrange donors for possible transfusions during chemotherapy.

MALIGNANT OVARIAN GERM CELL TUMORS AT A TERTIARY CARE SETTING IN PAKISTAN.

BACKGROUND: Malignant Ovarian Germ Cell Tumours (MOGCT) are rare neoplasms and their behavior is unknown in South-East Asian population. METHODS: Case records of 66 patients from 1994-2007 with MOGCT were reviewed. Histology was based on WHO classification. Tumours were staged according to International Federation of Gynecology and Obstetrics (FIGO) system. Data was collected on age, histopathology, stage, alpha-feto protein (AFP) and B-human chorionic gonadotropins (B-hCG) levels, treatment, time to recurrence (TTR) and overall survival (OS). OS was the interval in months between date of diagnosis and last encounter while TTR was between the date of diagnosis and recurrence. OS was determined by Kaplan-Meier method. RESULTS: Median age of our patients was 18 years. Ninteen patients were in stage I, eight in II, twenty-one in III and eighteen in stage IV. Histologically, dysgerminoma was the most common diagnosis (22 patients) followed by teratoma in 16, yolk sac tumor in 15, mixed germ cell tumor in 12 while embryonal carcinoma was identified in only one patient. Median followup was 48 months (0.2-183). All patients underwent initial surgery. Fertility sparing procedures were performed in 75% patients. Thirty-four patients (57.62%) achieved complete remission while 16 (27.11%) had progressive disease. Seven (10.60%) patients relapsed, all within first 3 years. TTR was 11.2-32.5 months. OS for study population was 60 months. Sixteen (88%) of stage I while only 4 (26.6%) of stage IV patients were alive at median follow-up. CONCLUSIONS: MOGCT has good prognosis with conservative surgery and platinum chemotherapy. Fertility sparing surgery has become a standard in MOGCTs, so awareness should be raised amongst professionals for early referral to cancer care facility.

Cancer Statistics from the Shaukat Khanum Memorial Trust's Hospital-based Cancer Registry, Pakistan, 1994-2022: An Observational Study.

Introduction: The Shaukat Khanum Memorial Trust has been operational, since February 1990. The first Shaukat Khanum Memorial Cancer Hospital and Research Center (SKMCH&RC) started functioning in Lahore on December 29, 1994. SKMCH&RC, Peshawar, started its operation in December 2015. The study aimed to give an overview of the cancer cases registered at SKMCH&RC over 28 years. Material and Methods: This study comprised patient data entered into the hospital information system after registration at the centers affiliated with the trust. The malignancies were stratified according to sex and age category (children [≤18 years] and adults [>18 years]). Results: Neoplasms of the breast, lower gastrointestinal (GI) tract, and lip and oral cavity were prevalent in all ages and both sexes combined; in adult females, neoplasms of the breast, ovary and uterine adnexa, and lip and oral cavity; in adult males, lower GI system, prostate, and lip and oral cavity; and in children, Hodgkin lymphoma, acute lymphoblastic leukemia, and non-Hodgkin lymphoma were predominant. Conclusion: Cases registered in a hospital-based registry are important. When combined with information from other facilities, they can estimate population-level statistics. This can improve cancer surveillance in the country for effective disease prevention, control, and management.

Using Telemedicine to Care for Patients with Breast Cancer: A Natural Quasi-Experimental Study.

Introduction: This investigation assessed the clinical characteristics of patients who received care through telemedicine and the clinical impact telemedicine service had on breast cancer patients in a low-income country. Materials and Methods: This natural experimental study assessed the impact of telemedicine service on cancer outcomes among breast cancer patients at Shaukat Khanum Memorial Trust (SKMT), Pakistan, between January 1st, 2018, to December 31st, 2022. The study group (hybrid group) consisted of patients that had both face-to-face and telemedicine appointments, and the control group (physical group) included patients with only face-to-face encounters. Results: A total of 3,205 patients were included in the analysis. Among those included in the analysis, 3,188 (99.5 %) were females, and the mean age of the cohort was 48.10 ± 11.94 years. Statistically significant differences were observed between the two groups in age, demographic distribution, disease stage, average number of emergency room visits, mean length of stay in the Intensive care unit, and the final patient status (alive at the end of observation period). However, the binary logistic regression model (forward-LR) suggested that the final patient outcome was related to disease relapse, COVID-19 infection, and age. Conclusion: Telemedicine clinics, when conducted in parallel with physical clinics (hybrid setup), are safe and have a clinical impact similar to having just physical encounters among breast cancer patients in a low-income country.

REPCAN: Guideline for REporting Population-based CANcer Registry Data.

Background: The objective of this study was to develop a guideline on how to report result of a population-based cancer registry. Methods: The guideline's development involved a core working committee and a scientific committee comprising experts from diverse domains. The process comprised three steps: 1) a comprehensive review of existing tools and guidelines and the development of the initial draft of the guideline based on a review of literature, 2) refinement items through several rounds of focus group discussion among the core group, and development initial draft, and 3) Evaluation of the initial draft by scientific committee members. Items in the guideline were organized to accommodate reports of population-based cancer registries as a scientific manuscript. Results: The core committee developed 47 items distributed in the major heading of a scientific manuscript presented as a checklist. The evaluation of the scientific committee led to a consensus on the majority of the items included in the checklist. Among 10 committee members, 7 provided unreserved approval, validating each item's necessity, applicability, and comprehensibility in the checklist. Feedback from the remaining 3 members was carefully analyzed and integrated to enhance the guideline's robustness. Incorporating feedback, a first final draft was presented in a meeting of scientific and core working committee members. Collaborative discussion ensured clarity of expression for each items and a final checklist was developed. Conclusion: The guideline abbreviated as REPCAN offers a standardized framework for reporting population-based cancer registry, fostering transparency, comparability, and comprehensive data presentation. The guideline encourages flexibility while promoting comprehensive and robust reporting practices.

Cancer in Faisalabad and Nankana Sahib, Pakistan: 2017-2019; An Observational Study.

Introduction: The Punjab Cancer Registry's catchment area includes the districts of Faisalabad and Nankana Sahib. It is an observational and descriptive study that covers the 3 years from 2017 to 2019, evaluating the distribution of cancer in these two districts. Material and Methods: Data on incident cancer cases diagnosed between 2017 and 2019 among residents of Faisalabad and Nankana Sahib in Pakistan, reported by the participating centres of the Registry, were reviewed retrospectively. Figures and proportions for adults, children and adolescents were computed. Results: During 2017 and 2019, 5678 cases were reported from Faisalabad and 390 from Nankana Sahib, with over 50% seen in females. In both districts combined, among adult females, cancers of the breast, reproductive system, and hepatobiliary system were commonly diagnosed, while cancer of the lip/oral cavity/pharynx, hepatobiliary system and non-Hodgkin lymphoma were the leading diagnoses among adult males. In children and young adults (0-19 years), acute lymphoblastic leukaemia, Hodgkin lymphoma and non-Hodgkin lymphoma were the most common diagnoses. Conclusion: The cancer distribution reported from Faisalabad and Nankana Sahib is of utmost importance. However, the underreporting of cancer cases cannot be ruled out. More input from the collaborators is needed to ensure the completeness of cancer surveillance in the region.

National Cancer Registry of Pakistan: First Comprehensive Report of Cancer Statistics 2015-2019.

OBJECTIVE: To compile a comprehensive national cancer registry report of Pakistan by merging and analysing cancer registration data received from major functional cancer registries in various parts of Pakistan. STUDY DESIGN: Observational study. Place and Duration of the Study: Health Research Institute (HRI), National Institutes of Health (NIH), Islamabad, from 2015-2019. METHODOLOGY: Data from major cancer registries which included 'Punjab Cancer Registry (PCR), 'Karachi Cancer Registry (KCR)', 'Pakistan Atomic Energy Commission (PAEC) Cancer Registry', Armed Forces Institute of Pathology (AFIP) Cancer Registry, Nishtar Medical University Hospital Multan (NMH), and Shifa International Hospital, Islamabad (SIH) registries were pooled, cleared, and analysed at HRI. RESULTS: A total of 269,707 cancer cases were analysed. Gender-wise 46.7% were males and 53.61% were females. As per province-wise distribution, 45.13% of cases were from Punjab, 26.83% from Sindh, 16.46% from Khyber Pakhtunkhwa (KP), and 3.52% from Baluchistan. Both genders combined, 'breast cancer' 57633 (21.4%) was the most common cancer. In males, the top-5 cancers in order of frequency/percenatages were 'oral' 14477 (11.6%), 'liver' 8398 (6.73%), colorectal 8024 (6.43%), 'lung' 7547 (6.05%) and 'prostate' 7322 (5.87% cancers). In females, causes of the top-5-cancers included 'breast' 56250 (38.8%), 'ovary' 8823 (6.09%), 'oral' 7195 (4.97%), 'cervix' 6043 (4.17%), and 'colorectal' 4860 (3.36%) cancers. In children 'Leukemia' 1626 (14.50%) and in adolescents 'Bone' 880 (14%) were the leading malignancies. CONCLUSION: Breast cancer is the most common cancer in females touching epidemic proportions while 'oral cancer' which is the leading cancer in males ranks third in frequency in females. Like 'oral cancer' which shows a strong correlation with chewing, other common cancers in Pakistan including liver cancer, lung cancer, and cervical cancer are also largely preventable as showed a strong correlation with hepatitis B and C, smoking, and high-risk human papillomavirus. KEY WORDS: National Cancer Registry, Health Research Institute - NIH, Islamabad, Pakistan.

Malignant phyllodes tumour of the breast.

BACKGROUND: Malignant Phyllodes Tumour (MPT) is considered to be a rare disease of the breast. The most frequent clinical presentation of a MPT is a rapidly growing breast lump. METHODS: Consecutive cases of MPT registered between Jan 1, 1995 and Dec 31, 2012 at the Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, were reviewed, to obtain information on age, tumour size, treatment given, disease-free survival, and overall survival. Disease-free survival was computed between the dates of surgery and recurrence, whereas, the overall survival time between the dates of diagnosis and last contact, both in months. RESULTS: A total of 101 cases of Phyllodes tumour were recorded. These included: malignant tumours (42) benign (27), and borderline (32). Malignant Phyllodes tumours (42 cases) were studied further and 41 included for additional analysis. The mean age of the women in the study was 40.3 +/- 12.5 (22-72 years). Of the 33 patients who were disease-free after surgery, 15 had a recurrence, whereas, 18 did not have a recurrence. In those who had surgery alone versus those who received radiation treatment in addition to surgery, the median disease-free survival was 117 and 44.2 months, respectively. The mean overall survival time was 33.7 months. CONCLUSION: In this study, patients presented at a younger age than in other studies. Further exploration into molecular, biologic, geographic, and socioeconomic factors is needed to clearly understand the epidemiology of this disease in our population.

Cancer in Lahore, Pakistan, 2010-2019: an incidence study.

OBJECTIVES: To study the cancer incidence rates over 10 years (2010-2019), in Lahore, Pakistan. DESIGN: An incidence study. SETTING: The population-based Punjab Cancer Registry was established in 2005 in Lahore, which is the provincial metropolis of the province of Punjab (five rivers), and is located in the northeast region of Pakistan. The coordinating office of the Registry is located within Shaukat Khanum Memorial Cancer Hospital and Research Center. Both the active and passive forms of data collection are used. PARTICIPANTS: Residents of the district of Lahore diagnosed with cancer. The average annual population of Lahore was estimated at 11.1 million. OUTCOME MEASURES: Cancer counts and incidence rates per 100 000 population, by age-group, sex and cancer site/type, over 10 years. RESULTS: In Lahore, from 2010 to 2019, 58 394 incident cases were reported, with the majority seen in females (57.1%). Adults accounted for 92.2%, adolescents 2.2% and children 5.6% of the total cases. Per 100 000 population, the age-standardised incidence rate was 103.4 for females and 65.6 for males. Among females, the highest incidence rates were recorded for breast cancer (76.7) in adults, bone tumour (1.2) in adolescents and lymphoid leukaemia (1.6) in children, and among males, prostate cancer (10.7) in adults, bone tumour (2.2) in young adults and lymphoid leukaemia (2.4) in children. The age-specific incidence rates peaked in the 60-70 year group, reaching a high of 420 per 100 000 in women and 330 per 1 00 000 men. CONCLUSIONS: In Lahore, the incidence rates for cancers of the breast, prostate, lymphoid leukaemia and bone were among the highest documented. More cases were recorded in females than in males. The results reported could be used as a reference point for assessing the effectiveness of future interventions.
