Background : With regard to the recurrence of esophageal cancer after surgery, the prognosis has improved with the progress of multimodal perioperative treatment. In this study, the recurrence pattern, treatment method, and prognosis of recurrent cases following esophageal cancer surgery were retrospectively examined. Materials and Methods : Three hundred seven patients with histologically proven squamous cell carcinoma, adenocarcinoma, and others were enrolled in the study. With respect to clinicopathologic factors and recurrence patterns, recurrence risk factors, recurrence period, treatment for recurrence, and prognosis were investigated.Results : Ninety two percent of all recurrent cases were observed within two years after radical esophagectomy. Locoregional recurrence, distant recurrence, and mixed recurrence were observed in 38 (35%), 56 (51%), and 16 (14%) cases, respectively. Patients with lymph node metastasis showed a significantly longer survival in comparison to those with metastasis to other organs (p = 0.0032). When analyzed using the treatment method, patients who underwent surgery (only surgery or additional postoperative chemotherapy) exhibited better survival in comparison to those who underwent other treatments. Discussion : Detailed and strict follow-up within two years are necessary in cases with deeper than muscular invasion, cases with extensive lymph node metastasis, or cases with lymphatic or vascular invasion.

Background: Human Lung Carcinoma (LC) is among the most diagnosed cancers across the world among those non-small cell lung cancer (NSCLC) comprises about 85%. Next Generation Sequencing based detection of mutations are now well established in molecular oncology. With the advent of modern diagnostic methods, it is now well known that there are several mutations and gene rearrangements which are associated with the development of LC.

Among the known nuclear exportins, CRM1 is the most studied prototype. Dysregulation of CRM1 occurs in many cancers, hence, understanding the role of CRM1 in cancer can help in developing synergistic therapeutics. The study investigates how CRM1 affects prostate cancer growth and survival.

Prader-Willi syndrome is a rare neurodevelopmental disorder that impacts the musculoskeletal, endocrine, pulmonary, neurologic, ocular, and gastrointestinal systems. In addition, individuals with Prader-Willi syndrome have issues with cognitive development, characteristic behavioral problems, and perhaps most profoundly, appetite control. Currently, the only US Food and Drug Administration-approved therapy for Prader-Willi syndrome is growth hormone, which has been Food and Drug Administration approved for > 20 years for the treatment of growth failure in Prader-Willi syndrome.

Recently, photodynamic therapy (PDT) which involves a photosensitizer (PS), a special drug activated by light, and light irradiation has been widely used in treating various skin diseases such as port-wine stain as well as cancers such as melanoma and non-melanoma skin cancers. PDT comprises two general steps: the introduction of PS into the body or a specific spot to be treated, and the irradiation process using a light source with a specific wavelength to excite the PS. Although PDT is gaining great attention owing to its potential as a targeted approach in the treatment of skin cancers, several limitations still exist for practical use.

Type 1 diabetes mellitus (T1DM) is characterized by the progressive, autoimmune-mediated destruction of β cells. As such, restoring immunoregulation early in the disease course is sought to retain endogenous insulin production. Nevertheless, in the more than 100 years since the discovery of insulin, treatment of T1DM has focused primarily on hormone replacement and glucose monitoring.
