We encountered a case of primary lung cancer complicated with membranous nephropathy as primary nephrotic syndrome. Because treatment approaches vary greatly for primary and secondary nephrotic syndrome, a renal biopsy was performed for diagnosis. Much time was required to make a definitive diagnosis of primary nephrotic syndrome, as opposed to paraneoplastic nephrotic syndrome. Consequently, the subsequent chemotherapy was ineffective and caused significant toxicity due to reduced performance status (PS) and progression of hypoalbuminemia. Therefore, it is imperative that a diagnosis be made and treatment be initiated without delay before PS declines and hypoalbuminemia progresses.

Background: Predictive factors for the development of dyspnea have not been reported among terminally ill cancer patients. Objective: This current study aimed to identify the predictive factors attributed to the development of dyspnea within 7 days after admission among patients with cancer. Methods: This was a secondary analysis of a multicenter prospective observational study on the dying process among patients admitted in inpatient hospices/palliative care units. Patients were divided into 2 groups: those who developed dyspnea (development group) and those who did not (non-development group). To determine independent predictive factors, univariate and multivariate analyses using the logistic regression model were performed. Results: From January 2017 to December 2017, 1159 patients were included in this analysis. Univariate analysis showed that male participants, those with primary lung cancer, ascites, and Karnofsky Performance Status score (KPS) of ≤40, smokers, and benzodiazepine users were significantly higher in the development group. Multivariate analysis revealed that primary lung cancer (odds ratio [OR]: 2.80, 95% confidence interval [95% CI]: 1.47-5.31; p = 0.002), KPS score (≤40) (OR: 1.84, 95% CI: 1.02-3.31; p = 0.044), and presence of ascites (OR: 2.34, 95% CI: 1.36-4.02; p = 0.002) were independent predictive factors for the development of dyspnea. Conclusions: Lung cancer, poor performance status, and ascites may be predictive factors for the development of dyspnea among terminally ill cancer patients. However, further studies should be performed to validate these findings.

Rare Lesion

Endotracheal metastasis, a critical complication of primary lung cancer, is an extremely rare lesion. A 73-year-old woman who had previously received treatment for lung cancer presented to our emergency department with dyspnea. A chest computed tomography and nasopharyngolaryngoscopy showed an endotracheal mass below the epiglottis, obstructing the trachea almost completely. The patient had an emergency tracheostomy, and then the mass was removed via median laryngotomy. This lesion was proven to be a recurrent metastasis of lung cancer. Clinicians should recognize endotracheal metastasis as an important differential diagnosis in cancer patients presenting with respiratory symptoms.

e17508 Background: Lung cancer remains uncommon among young adults but it causes great loss of life expectancy in this age group. The definition of young age varies in the published studies from 40 to 50 years of age. Methods: Our aim was to assess whether patients diagnosed at young ages have unique clinicopathological and prognostic characteristics. We retrospectively reviewed records of patients aged 45 or younger who were treated for primary lung cancer at a large tertiary center between June 2003 and June 2011. Results: 2,651 patients with lung cancer were screened of whom 73 (2.8%) were aged ≤45. The male-to-female ratio was 1.6:1 and the median age at diagnosis was 42. 89% of patients were smokers. Performance status (PS) was 0, 1 and 2 in 61%, 29% and 10% of patients, respectively. The most common histological types were adenocarcinoma (47%), small-cell lung cancer (SCLC) (18%) and squamous cell carcinoma (18%). The median time elapsing between beginning of symptoms and diagnosis was 3 months. Chronic hepatitis B or C was mentioned in the medical history of 5/13 (38%) SCLC patients, whereas it was present in 4/60 NSCLC patients under 45 (p=0.008) and in 16/518 SCLC patients over the age of 45 (p<0.0001). Patients were diagnosed with stages I, II, III and IV in 2 (3%), 11 (18%), 13 (22%) and 34 (57%) of NSCLC cases, respectively, whereas 7 of 13 (54%) SCLC patients were diagnosed with limited disease. The median overall survival was 21 months and multivariate analysis indicated that PS and time until diagnosis were independent prognostic factors. Conclusions: Although more than half of young patients are at stage IV when diagnosed, prognosis does not seem as dismal as previously considered. Larger studies need to be conducted in order to elucidate the possible role of chronic hepatitis in the pathogenesis of SCLC in young patients.

e19078 Background: In recent years, many major advances have been made in non-small-cell lung cancer (NSCLC), and in particular in adenocarcinoma, but not in SCLC. In 2010, the French College of General Hospital Respiratory Physicians (CPHG) performed a prospective multicentre epidemiological study (KBP-2010-CPHG) to describe the baseline characteristics and management of all new cases of primary lung cancer and to evaluate survival. The present abstract reports results in SCLC patients. Methods: 7,051 patients ≥18 years presenting with a new case of primary lung cancer, histologically or cytologically diagnosed between 1 January and 31 December 2010 and managed in the respiratory department of one of the 104 general hospitals participating in the study, were included. A standardised form was completed for each patient. A steering committee checked data collection exhaustiveness. SCLC data were analysed separately. Results: There were 968 SCLC patients: mean age, 65.6 years (+/-10.6); 23.2% female; 4.4% non-smokers (11 % in women), 35.8% ex-smokers, 59.8% current smokers; 63.4% with performance status 0 or 1; 59.9% having lost weight within the previous 3 months (19.8% of whom had lost >10 kg). Main tumour characteristics at diagnosis were: 71.2% stage IV, 24.7% stage IIIA or IIIB, 4.1% of stage <III. 15.2% of patients received chemo-radiotherapy and 73.4% chemotherapy (86.2% platinum-based). Carboplatin was more commonly used in patients >70 (59.1%) than <70 years of age (40.9 %). One-year mortality was 64.2%. Compared with NSCLC patients, patients with SCLC more frequently were active smokers (59.8% vs.47.6%), lost weight (59.9% vs. 52.4%), and presented with stage IV tumour at diagnosis (71.2% vs. 58.3%); first line therapy was more frequently platinum-based chemotherapy (86.2% vs. 61.2%) and less frequently curative surgery (1.6% vs. 19%), and mortality was higher (64.2% vs. 55.2%). Conclusions: In 2010, prognosis remains poor in SCLC. Compared with NSCLC, it was more frequently associated with active smoking and stage IV disease, and showed a lower rate of surgery.

Abstract Background In lung cancer management, differential diagnosis between multiple primary lung cancer (MPLC) and intrapulmonary metastasis (IMP) is a critical point that is of direct therapeutic and clinical importance. However, this process often suffers from absence of a gold standard, resulting in equivocal cases. Herein, we present a series of three cases, in which genomic alteration patterns revealed by next-generation sequencing (NGS) facilitated the differential diagnosis between MPLC and IMP. Case presentation Case 1 was a 57-year-old female with two separate lesions in the upper lobe and the lower lobe of left lung, which were both histopathologically determined as T2aN0M0 adenocarcinomas. NGS identified an EGFR L858R in one lesion and an EGFR 20 exon insertion in the other one, suggestive of double primary malignancies. The patient underwent wedge resections and received an adjuvant treatment of icotinib and chemotherapy. She had a disease-free survival (DFS) of 19 months and counting. Case 2 was a 55-year-old female with multiple small lesions in both lungs. Histopathological examinations of resected lesions from right upper lobe revealed three subtypes: atypical adenomatous hyperplasia of alveolar epithelium, adenocarcinomas in situ and minimally invasive adenocarcinoma. NGS identified two different BRAF driver mutations G466E and V600_K601delinsE in two lesions of adenocarcinoma in situ, and a BRAF K601E in a lesion of minimally invasive adenocarcinoma. Case 3, a 68-year-old male, had the right upper lobe lesion histophathologically classified as a stage T3NxM0 mixed adenoneuroendocrine carcinoma and the left upper lobe lesion as a stage T1aN0M0 adenocarcinoma. NGS performed with different loci of surgical tissues revealed a rare sensitizing EGFR mutation G719A shared by the right upper lobe lesion and lymph node, and two EGFR mutations L861Q and G719S in left upper lobe lesion. The patient received icotinib treatment postoperatively and achieved a stable disease with a progression-free survival of 5 months. Conclusion Our cases provide evidence for utility of NGS in facilitating diagnosis and treatment decisions.

Lung Cancer Survival

Background Lung cancer is the leading cause of cancer-related mortality worldwide. Demographic differential has been linked with the treatment outcome and survival in recent literature, mostly from the developed world. Considering diversity in population characteristics across income strata, it’s worth assessing the link in low- and middle-income population as well. Current study aimed to assess the association of demographic characteristics with lung cancer survival in Bangladeshi lung cancer patients. Methods & results All newly diagnosed primary lung cancer cases attending the national institute of cancer research & Hospital (NICRH), a tertiary cancer care center in Dhaka, Bangladesh between 2018 and 2019 were considered for the study. Demographic information and clinical data were obtained from the patients’ medical records by a trained physician. Survival estimate was generated using the Kaplan-Meier method and compared across demographic and clinicopathological categories using the log-rank test. Hazard ratio and 95% CI for treatment options are generated fitting multivariable Cox proportional hazard regression. Among 1868 patients, 84.6% were males and 15.4% were females, average (± standard deviation) age at diagnosis was 59.6±10.9 years, only 10.8% had not consumed tobacco of any form. Around two-thirds of the patient had Eastern Cooperative Oncology Group (ECOG) performance score ≥2, 29.5% had at least one comorbidity and 19.4% had metastasis at the time of presentation. Higher survival was associated with institutional education (HR 0.9; 95% CI 0.77, 0.99), and receipt of combined radiotherapy and chemotherapy (HR 0.56; 95% CI 0.46, 0.65; p <0.001). In contrast, lower survival was associated with older age between 60–69 years (HR 1.3; 95% CI 1.3, 1.5;), age ≥ 70 years (HR 1.4; 95% CI 1.1, 1.7), having any comorbidity (HR 1.1; 95% CI 1.0, 1.3), with ECOG score ≥ 3 (HR 1.41; 95% CI 1.01, 1.96) and receipt of radiotherapy treatments only (HR 1.6; 95% CI 1.3, 1.9). Conclusion Older age, presence of one or more comorbidity, poorer performance status, and treatment with only RT appeared as a significant predictor of poorer prognosis of lung cancer in Bangladeshi patients. In contrast, having institutional education and treatment with combined Radiotherapy and Chemotherapy appeared as a predictor of a better prognosis. The finding of this study could serve as a basis for future studies inquiring into novel approaches for certain subgroups of patients believed to be challenged in limited resources.

Accounting for about 20 to 50% of cases of primary nephrotic syndrome, membranous nephropathy (MN) is the leading cause of nephrotic syndrome in adults. A rat model created nearly 60 years ago to research the primary MN disorder, Heymann nephritis, has provided us with a plethora of important information. Recently, our knowledge about MN has dramatically progressed. Heymann nephritis and human MN are now known to share a high degree of similarity in pathogenesis. This review summarizes our current understanding of MN pathogenesis while focusing particularly on the immunological aspects.

Purpose: Lung cancer is the leading cause of cancer death worldwide. The objective was to analyze survival for lung cancer in Granada, and to identify the factors influencing survival. Methods: Data were obtained from the population-based cancer registry in Granada (Spain). All cases of newly diagnosed primary lung cancer in 2011-2012 (n=685) were included. One and two-year relative survival was estimated. Results: Of our population, 65% of the patients were over 65 years of age, and 83% were men. 74% of patients had good performance status (PS); 81% of the tumors were microscopically verified; and 81% were non-small cell lung cancer. Overall, 16% were stage I-II, whereas 57% were stage IV. Radiotherapy was administered in 28% of cases, chemotherapy in 45%, whereas 23% of patients were operated. The two-year survival rate was 18% (67% and 5% for stage I and IV). Survival was higher among women (29%), <75 years of age (21.6%), and those with good PS (23%). Microscopic verification and surgery led to higher survival rates of 23.4% and 69%, respectively. Conclusions: Since the factors affecting survival were PS, stage, and surgery, efforts should target the early diagnosis of lung cancer since this would improve treatment options and outcomes.
