Background: Cancer has become a major health problem associated with high mortality worldwide, especially in developing countries. The aim of our study was to evaluate the incidence rates of different types of cancer in Sulaymaniyah from January-2006 to January-2014. The data were compared with those reported for other middle east countries. Materials and Methods: This retrospective study depended on data collected from Hiwa hospital cancer registry unit, death records and histopathology reports in all Sulaymaniyah teaching hospitals, using international classification of diseases. Results: A total of 8,031 cases were registered during the eight year period, the annual incidence rate in all age groups rose from 38 to 61.7 cases/100,000 population/year, with averages over 50 in males and 50.7 in females. The male to female ratio in all age groups were 0.98, while in the pediatric age group it was 1.33. The hematological malignancies in all age groups accounted for 20% but in the pediatric group around half of all cancer cases. Pediatric cancers were occluding 7% of total cancers with rates of 10.3 in boys and 8.7 in girls. The commonest malignancies by primary site were leukemia, lymphoma, brain, kidney and bone. In males in all age groups they were lung, leukaemia, lymphoma, colorectal, prostate, bladder, brain, stomach, carcinoma of unknown primary (CUP) and skin, while in females they were breast, leukaemia, lymphoma, colorectal, ovary, lung, brain, CUP, and stomach. Most cancers were increased with increasing age except breast cancer where decrease was noted in older ages. High mortality rates were found with leukemia, lung, lymphoma, colorectal, breast and stomach cancers. Conclusions: We here found an increase in annual cancer incidence rates across the period of study, because of increase of cancer with age and higher rates of hematological malignancies. Our study is valuable for Kurdistan and Iraq because it provides more accurate data about the exact patterns of cancer and mortality in our region.

Background: Research evidence suggests a debilitating impact of the diagnosis of cancer on the quality of life of the afflicted individuals, their spouses and their families. However, relatively few studies have been carried out on the impact on the QOL of adolescents living with parents diagnosed with cancer. This paper presents a sub-analysis on the impact of parental cancer (colorectal, breast and lung) on adolescents. Materials and Methods: This is a cross-sectional study on adolescents aged 13-18 years old. Upon ethical clearance obtained from UMMC Medical Ethics Committee, patients with colorectal, breast or lung cancer and their adolescent children were recruited from the Clinical Oncology Unit of University of Malaya Medical Centre. Respondents who gave consent completed a demographic questionnaire and the Pediatric Quality of Life Inventory, via the post, email, home visit or meetings at the clinics. Results: 95 adolescents from 50 families responded, giving a response rate of 88 percent. The adolescent's mean age was 16 years (ranging between 13-18 years). Adolescents with parental cancer had the lowest mean score in emotional functioning (p<0.05). Male adolescents had significantly higher quality of life overall and in physical functioning compared to female adolescents. Adolescents with a father with cancer had better school functioning compared to adolescents whose mothers had cancer. Families with household income of RM 5000 and above have significantly better quality of life compared to families with lower household income. Conclusions: Adolescent sons and daughters of parents with a cancer diagnosis show lowered QOL, particularly with reference to emotional functioning and school performance. Addressing the needs of this young group has been slow and warrants special attention. Revisiting the risk and resilience factors of adolescents might also inform tailored programs to address the needs of this neglected adolescent population.

Background: Prevalence is a statistic of primary interest in public health. In the absence of good follow-up facilities, it is difficult to assess the complete prevalence of cancer for a given registry area. Objective: An attempt was here made to arrive at complete prevalence including limited duration prevalence with respect to selected sites of cancer for India by fitting appropriate models to 1, 3 and 5 years cancer survival data available for selected population-based registries. Materials and Methods: Survival data, available for the registries of Bhopal, Chennai, Karunagappally, and Mumbai was pooled to generate survival for breast, cervix, ovary, lung, stomach and mouth cancers. With the available data on survival for 1, 3 and 5 years, a model was fitted and the survival curve was extended beyond 5 years (up to 35 years) for each of the selected sites. This helped in generation of survival proportions by single year and thereby survival of cancer cases. With the help of survival proportions available year-wise and the incidence, prevalence figures were arrived for selected cancer sites and for selected periods. Results: The prevalence to incidence ratio (PI ratio) stabilized after a certain duration for all the cancer sites showing that from the knowledge of incidence, the prevalence can be calculated. The stabilized P/I ratios for the cancer sites of breast, cervix, ovary, stomach, lung, mouth and for life time was observed to be 4.90, 5.33, 2.75, 1.40, 1.37, 4.04 and 3.42 respectively. Conclusions: The validity of the model approach to calculate prevalence could be demonstrated with the help of survival data of Barshi registry for cervix cancer, available for the period 1988-2006.

Purpose : To compare the dosimetry for the left breast cancer treatment between three dimensional conformal radiation radiotherapy (3D-CRT) and Hybrid planning and to estimate usefulness of Hybrid planning Materials and Methods : Five patients with left breast cancer were included in the study. They were planned using several different radiotherapy techniques including: 1)open rectangular field, 2)tangential wedge-based field 3)field in field, 4)hybrid planning(energy, wedge combine). For each patient planning was using Light Speed RT-16 CT and PINNACLE planning system-ver.9.2. Hybrid plan was made using same system and using the same targets and optimization goals. We comparing the Homogeneity Index(HI), normal organs at the does-volume histogram(DVH) Results : In all plans, the Homogeneity Index(HI) of Hybrid planning was significantly better than other. Dose comparison of HI= 2D-RT:38.32, TW:38.32, FIF:29.22, HYBRID:30.57. 2D-RT, TW, FIF Hybrid$V_{75_-lung}$=112.33, 125.14, 121.3, 123.78. $V_{50_-lung}$=155.43, 159.62, 157.96, 159.06. $V_{25_-lung}$=199.86, 200.22, 198.65, 200.31. $V_{50_-heart}$=26.07, 27.1, 26.85, 27.17 $V_{30_-heart}$=33.71, 34.37, 34.15, 34.65 Conclusion : In summary, 3D-CRT, Hybrid planning techniques were found to have acceptableCTV coverage in our study. However the Hybrid planning increased radiation dose exposure to normal tissue. If you apply for treatment of inhomogeneity areas like lung, For best results will be achieved.

Although chimeric antigen receptor T cell (CAR-T) is a promising immunotherapy in hematological malignancies, there remain many obstacles to CART cell therapy for solid tumors. Identifying appropriate tumor-associated antigens (TAAs) is especially critical for success. Using a bioinformatics approach, we identified common potential TAAs for CAR-T cell immunotherapy in solid tumors. We used the GEO database as a training dataset to find differentially expressed genes (DEGs) and verified candidates using the TCGA database, obtaining seven common DEGs (HM13, SDC1, MST1R, HMMR, MIF, CD24, and PDIA4). Then, we used MERAV to analyze the expression of six genes in normal tissues to determine the ideal target genes. Finally, we analyzed tumor microenvironment factors. The results of major microenvironment factor analyses showed that MDSCs, CXCL1, CXCL12, CXCL5, CCL2, CCL5, TGF- β, CTLA-4, and IFN-γ were significantly overexpressed in breast cancer. The expression of MST1R was positively correlated with TGF- β, CTLA-4, and IFN-γ. In lung adenocarcinoma, MDSCs, Tregs, CXCL12, CXCL5, CCL2, PD-L1, CTLA-4, and IFN-γ were significantly overexpressed in tumor tissues. The expression of MST1R was positively correlated with TGF- β, CTLA-4, and IFN-γ. In bladder cancer, CXCL12, CCL2, and CXCL5 were significantly overexpressed in tumor tissues. MST1R expression was positively correlated with TGF- β. Our results demonstrate that MST1R has the potential as a new target antigen for treating breast cancer, lung adenocarcinoma, and bladder cancer and may be used as a progression indicator for bladder cancer.

Breast cancer is one of the most common cancers and causes several complications in females. Currently, MRI is a necessary method for preoperative studies in patients with breast cancer. A high frequency of breast MRI can lead to an increase in the number of incidental extramammary findings. Moreover, it can provide accurate preoperative workup; therefore, the prognosis of patients can be improved. Herein, we provide several extramammary findings, including the mediastinum, lung, upper abdomen, bone, and soft tissue, correlating with US, chest CT, liver MRI, PET-CT, and bone scan.

Purpose: DBC2 (Deleted in Breast Cancer 2) has been indicated to be a tumor suppressor gene in many cancers including lung adenocarcinoma recently. In this study, we aimed to explore the expression status of DBC2 in different subtypes of lung adenocarcinoma (from pre-invasive to invasive lesions), and to determine if downregulation becomes more marked with pathological progression. Methods: We collected 172 tissue samples from different subtypes of lung adenocarcinoma and investigated the frequency of DBC2 loss by immunohistochemistry. Results: Our results indicated that DBC2 downregulation is a relatively frequent event in lung adenocarcinoma. Moreover, as the adenocarcinoma subtype turns to be more invasive, more downregulation occurred. Conclusion: We conclude that loss of DBC2 expression is an early and progressive event in the pathogenesis of lung adenocarcinoma. Positive DBC2 immunohistochemistry may become an indicator for early stage disease and better prognosis of lung adenocarcinomas.

In spite of recent progress in anticancer chemotherapy, the survival of patients with metastases to the lung treated nonsurgically has been extremely poor. So we adopted more aggressive surgical approaches for the treatment of patients with pulmonary metastases since 1985. We experienced 22 operations of metastatic lung cancer in 19 patients in the department of Thoracic & Cardiovascular Surgery in Kosin Medical College since 1985, so we reviewed the results of treatment retrospectively. The results were as follows: 1. The primary organs of metastatic lung cancer were 4 cases in each of the breast, uterus, and extremities, 3 cases in the rectum, 2 cases in the kidney, 1 case in each of the pelvis and liver, and the pathological findings were 13 cases in carcinoma and 6 cases in sarcoma. 2. The treatments for primary lesions were 15 cases of the operations with anticancer chemotherapy or radiation therapy, 2 cases of choriocarcinoma with anticancer chemotherapy only, 1 cases of uterine cervical carcinoma with chemo-radiation therapy, and 1 case of pelvic synovia sarcoma with intra-arterial anticancer chemotherapy. 3. Disease free intrerval were as follows: 7 cases were in 2 years to 4 years, 4 cases were in 1 year to 2 years, and 5 cases were beyond one year, of them one case was discovered primary lesion and metastatic lung tumor concomittently. 3 cases were above 4 years, of them one case of breast cancer were above 13 years especially. 4. The sites of metastatic lung cancer was 15 lesions in the right lung, and 9 lesions in the left lung, And the lobar sites were 10 lesions in the upper lobe, 2 lesions in the middle lobe, and 12 lesions in the lower lobe. 5. The operative methods of metastatic lung cancer were 7 case of partial resection of lung, 12 cases of pulmonary lobectomy, 1 case of pneumonectomy and 1 case of dissection of mediastinal lymph node. 6. The postoperative complications were 1 case of mild respiratory insufficency, 1 cases of pyothorax, and 1 case of urethral stricture. 7. Postoperative adjuvant therapy were as follows: No adjuvant therapy were 4 cases, anti-cancer chemotherapy were 8 cases, radiation therapy was 1 case, and combined with chemo k radiation therapy were 8 cases. 8. The results of long term follow-up were as follows: The 5 patients were died at 2 months, 22 months, 24 months, 32 months, and 49 months postoperatively, so mean survival period was 32 months postoperatively excluding one patient who was died at 2 months postoperatively. And 14 patients are aliving, of them 3 patients are living in recurred state, and the other 11 patients are living without any evidence of recurrence.
