Background: Lung cancer is one of the commonest cancers and cause of cancer related deaths all over the world. The reported incidence of adenocarcinoma is increasing globally and now reported to be the most common type of lung cancer. A panel of investigations are used for the diagnosis of lung cancer. Hence a study was planned to find out the pattern of malignancy and the most appropriate investigation for diagnosis. Objective of present study was to find out the type of carcinoma lung and to find out the best and easy method for diagnosis of carcinoma lung in a tertiary care centre.Methods: A hospital based cross sectional study was conducted in one unit of the Department of Pulmonary Medicine, Government Medical college, Thiruvananthapuram for a period of one year.148 diagnosed cases of carcinoma lung were enrolled. The type and the methods used for diagnosis were analysed.Results: Adenocarcinoma was the commonest malignancy 57 (38.5%), followed by squamous cell carcinoma 44 (29.7%) and small cell carcinoma 10 (6.75%). Rest of the cases 37 (25%) include non small cell carcinoma, poorly differentiated carcinoma and lymphoma. Diagnosis was established by FNA Lung in 46 (31.1%) patients and bronchoscopy and biopsy in 41 (27.7%). Other methods include TBNA 12 (8.1%), lymph node FNA/biopsy 11 (7.4%), pleural fluid cytology 24 (16.2%), sputum cytology and tru cut biopsy 14 (9.5%).Conclusions: The most common type of lung malignancy in present study was adenocarcinoma. Ultra sound guided FNAC lung and bronchoscopy biopsy were the best methods in present study to confirm the diagnosis.

Carcinoma Of The Bladder

Primary small-cell carcinoma arising from the bladder (SmCCB) is uncommon. It differs from urothelial carcinoma (UC), the most common type of bladder cancer, with respect to its cell of origin, biology, and prognosis. Biologically, prostatic SmCCB is much more aggressive than UC, and the prognosis for cases with distant metastasis is especially poor. We report here a case of primary SmCCB (cT3bN1M0) treated with radical cystectomy.

e17505 Background: Lung cancer ranks among the most common and lethal malignancies worldwide and also in India. There are geographic and ethnic variations in incidences, clinical and pathological profile of lung cancer. There is paucity of data of changing trend of pathological and clinical profile from this part of the world. Methods: A total of 434 patients with lung cancer were analyzed who were registered at All India Institute of Medical Sciences, over a 3 year period, from July 2008 till June2011, based on information in hospital records. Survival analysis was performed on 310 patients who have received at least one modality of treatment. Results: Median age of the whole cohort was 55 years (23-84 years). There were 357 (82.26%) males and 77 (17.74%) females, 295(69.91%) smokers and 127 (30.09%) non smokers. 370 (85.25%) patients had NSCLC and 64 (14.74%) had SCLC. Among NSCLC, adenocarcinoma was the commonest histology (45.41%) followed by squamous cell carcinoma (29.46%) and unclassified NSCLC (20.54%). Majority (66.13%) of the diagnosis were based on biopsy (needle or bronchoscopic). Among NSCLC, 26.3% patients were of stage 1-3A and 73.7% were of stage 3B and 4. Among SCLC 25% patients were of limited stage and 75% patients were of extensive stage. 73.18% of NSCLC patients received chemotherapy, 19.15% received TKI and 5.75% received RT as first line treatment modality. Among SCLC 93.88% received chemotherapy and 6.12% received RT as first line treatment. Median PFS and OS of patients with NSCLC were 7.8 months and 13.2 months respectively while that of SCLC were 6.1 months and 9.2 months respectively. Conclusions: Pathological profile of lung cancer has changed in India. Adenocarcinoma has become the commonest histology, contrary to the older reports when squamous cell carcinoma was more common. Majority of the patients are diagnosed in advanced stage and survival of these patients remains poor.

<abstract> <p>Lung cancer is one of the most common tumors. There are 1.8 million new cases worldwide each year, accounting for about 13% of all new tumors. Lung cancer is the most important cause of cancer-related deaths. 1.4 million people die of lung cancer each year. This article uses artificial intelligence technology to analyze the pathology of hesperetin-derived small cell lung cancer under fiberoptic bronchoscopy. This article takes 48 lung slice samples as the research object. Among them, 36 cases of lung small cell carcinoma have history slices from Lhasa City Institute of Biology, the patient has complete cases, and the other 12 normal lung slices come from Xinjiang Biotechnology Laboratory. In this paper, the above-mentioned 36 lung cancer slices became the study group, and 12 normal slices became the reference group. This article presents a method for hesperetin-fiber bronchoscope to study the pathological mechanism of lung small cell carcinoma (H-FBS), which is used to study slices. The above-mentioned 48 samples were taken for slice observation. First, the 48 slices were technically tested by artificial intelligence fiber bronchoscope combined with hesperetin derivatives, and then the slice observation results were verified by CTC technology. In addition, in each step, the C5orf34 in the tissue is detected separately, which is beneficial to adjust the content of C5orf34 so that the treatment of lung cancer can control the development of lung cancer under fiberoptic bronchoscopy. Experimental results show that the diagnostic accuracy rate of this method is 97.9%, which is higher than that of lung biopsy (89%); compared with multiple CTC detection, the cost is low and the time is shor.</p> </abstract>

The most common cause of an Opaque Hemithorax is Pleural Effusion. It is a rare occurrence to find patients with extensive mass leading to an opaque hemithorax. Thorough search of literature did not yield any case with such a large lung mass leading to opaque hemithorax, without the presence of pleural effusion. Lung cancer is the most common cancer diagnosed worldwide and has predominantly been attributed to tobacco smoke exposure. Of the several types, small cell lung cancer differs from others by its early spread and extensive dissemination leading to metastatic classification at the time of diagnosis. Here, is a case of a 50-year-old female patient who presented to the outpatient department with dry cough, weight loss and appetite loss since five months. Her chest radiograph revealed a right-sided homogeneous opacity involving the entire right hemithorax and left-sided pleural-based homogenous mass. Contrast Enhanced Computed Tomography (CECT) thorax revealed an enlarged hemithorax with evidence of large, ill-defined heterogeneously enhancing multilobulated soft-tissue density mass lesion occupying the entire right hemithorax. Biopsy was suggestive of Small Cell Carcinoma of Lung (SCLC), chemotherapy was given and patient is under regular follow-up.

Introduction. Lung cancer is one of the most common malignant neoplasms, as well as the most common cause of death cancer. Most lung cancers are squamous cell carcinomas, small cell carcinomas or adenocarcinomas. Objective. Examining changes in trends of lung cancer incidence in Montenegro by histological type during a 15-year period, from 1997 to 2011. Methods. During the study period, histopathological confirmation was obtained for all primary lung cancer cases in the only hospital for lung diseases in the country. Based on the data from medical records, patients were classified by time period, sex, age groups and smoking history. Descriptive method was used. Results. Ratio between incidences of adenocarcinoma and squamous cell carcinoma changes in males, with a significant increase in the incidence rate of adenocarcinoma and drop in the rate of squamous cell carcinoma (p<0.001). In addition, statistically significant (p<0.05) decrease in the incidence of NSCLC (non-small cell lung cancer) and an increase in the incidence of SCLC (small cell lung cancer) was found. A statistically significant increase in linear trend in the incidence of small cell carcinoma was noted in females (p<0.005). Conclusion. Incidence rates of adenocarcinoma and small cell carcinoma have increased during the study period.

Atrial Natriuretic

Euvolemic hyponatremia in the setting of lung cancer is most commonly due to the syndrome of inappropriate anti-diuretic hormone secretion (SIADH). However, a subset of patients with small cell carcinoma and hyponatremia also have elevated levels of atrial natriuretic peptide (ANP), which is produced by some small cell tumors. We report the case of a 64-year-old man with a limited-stage small cell carcinoma of the lung undergoing chemoradiation therapy, who was admitted to hospital with a pulmonary embolism. Two months earlier, at the time of diagnosis with lung cancer, he had a hypotonic, euvolemic hyponatremia, presumed to be caused by SIADH. At that time, his serum sodium readily normalized with fluid restriction and ADH-antagonist therapy with demeclocycline. However, during his second admission, the hyponatremia was refractory to treatment: his sodium level slowly declined from 138 mmol/L to a nadir of 118 mmol/L, despite early initiation of fluid restriction and maximal doses of demeclocycline. Laboratory values revealed a low but inappropriately non-zero level of ADH but also an inappropriately low level of aldosterone and an elevated level of ANP, suggesting that SIADH might not be the only contributor to the hyponatremia. While a causal link between ectopic ANP production and hyponatremia has never been established, an inappropriately high level of ANP can directly decrease sodium re-absorption in the proximal convoluted tubule of the kidney and increase glomerular filtration rate (GFR), resulting in greater excretion of sodium and water. In addition, high circulating levels of ANP can inhibit aldosterone secretion, potentially resulting in further sodium wasting. Here, the elevated ANP and inappropriately low aldosterone suggested the possibility that the refractory hyponatremia, although initiated by SIADH, was further worsened by an ANP-mediated natriuresis and suppression of aldosterone response.
