Objective To explore the prognostic factors for primary gastric diffuse large B cell lymphoma (PG-DLBCL). Materials and Methods This retrospective study analyzed 72 PG-DLBCL patients between January 2012 and December 2017 in Shanxi Cancer Hospital of Shanxi Medical University, so as to identify the different prognostic factors in PG-DLBCL. The clinical features, treatment and follow-up information were analyzed. Results The low CD4CD8 ratio group (median subsequent OS = 36.06 months; 95% confidence interval [CI] = 25.73-46.40) showed a significant decrease in subsequent OS compared to the normal group in PG-DLBCL patients who were newly diagnosed and did not receive rituximab (median OS = 52.58 months; 95% CI = 44.18-60.97; p = 0.029). EFS24 also decreased significantly in the low CD4CD8 group (median EFS24 = 16.27 months; 95% CI = 13.09-19.45) compared to the normal group (median EFS24 = 20.34 months; 95% CI = 17.05-23.63; p = 0.014). Multivariate analysis showed that low CD4CD8 at diagnosis was an independent poor prognostic factor for subsequent OS and EFS24. Conclusion Our data suggested that identifying prognostic factors, especially host immunity, may provide useful information for assessing prognosis or clinical management.The patient was a 43-year-old man. At 30 years of age, he underwent high-inguinal orchiectomy for a right testicular tumor and was diagnosed with seminoma pT1N0M0. The patient had been followed without additional treatment and had dropped out 7 years after surgery. At 43 years of age, abdominal ultrasonography performed for screening revealed a swollen 4 cm-wide intra-abdominal lymph node, and he was referred to our department. Abdominal contrast-enhanced computed tomography (CT) showed a mass with a 5 cm-wide contrast effect that contacted the anterior surface of the inferior vena cava from the duodenum to the aortic bifurcation. Histological examination by trans-duodenal ultrasound-guided fineneedle aspiration suggested late recurrence of seminoma. Guanosine After receiving three courses of BEP (bleomycin, etoposide, and platinum) therapy, the patient underwent laparoscopic lymphadenectomy. Pathological examination showed no residual tumor, and the patient was free of recurrence at 13 months after surgery.A 64-year-old man was diagnosed with metastatic prostate cancer (cT3bN0M1b) and treated with combined androgen blockade. After two years and three months, he developed castration-resistant prostate cancer. Multiple lung metastases appeared after the administration of five courses of docetaxel and four courses of cabazitaxel therapy. Pulmonary metastases disappeared following rechallenge with docetaxel. Enzalutamide administration was initiated because docetaxel had to be discontinued due to adverse events. Although enzalutamide lowered the prostate specific antigen value, the patient staggered while walking and developed homonymous hemianopsia. Magnetic resonance imaging revealed a brain tumor. Although the brain tumor was considered to have metastasized from the prostate cancer, it was diagnosed as a primary central nervous system lymphoma using open-ended tumor biopsy. The brain tumor was eliminated with whole-brain irradiation. Thereafter, he has been treated with enzalutamide for 3 years without clinical progression of either disease.Ten years ago, a seventy-year-old female underwent extirpation of a left retroperitoneal tumor that was 58×36 mm in size. The pathological diagnosis was malignant peripheral nerve sheath tumor (MPNST) at that time. The patients visited our hospital with the chief complaint of back pain at ten years after surgery. Computer tomography (CT) showed recurrent tumors at the pancreas and the left kidney. Fine-needle aspiration biopsy was performed because of the possibility of pancreatic tumor. The pathological diagnosis was the recurrence of MPNST. The patient underwent extirpation of the recurrent tumors along with the pancreatic body and tail, transverse colon, spleen and left kidney. The definitive diagnosis was dedifferentiated liposarcoma with murine double minute 2 (MDM2) gene amplification and positive of p16Ink4 (p16). The previously resected tumor also revealed MDM2 gene amplification and positive of p16. Based on these results, our diagnosis in this case was recurrence of dedifferentiated liposarcoma. At 6 months after surgery, the patient had no local recurrence or distant metastases.Psoas muscle mass index (PMI) is related to sarcopenia. We examined whether PMI is associated with early complications after radical cystectomy. Seventy one male and 29 female patients who were 65 years old or older and who had undergone radical cystectomy at our hospital from April 2005 to March 2018 were retrospectively analyzed. Psoas muscle section area was measured manually on preoperative computed tomography (CT) scan and normalized by patient's height. Early postoperative complications of grade 3 or more occurred in 12 male (16.9%) and 5 female (17.2%) patients. PMI was lower in male patients who had early postoperative complications of grade 3 or more than in those without complications (5.61 vs 6.54 cm2 /m2, p=0. 08), although the difference was not statistically significant. There was suggested to be a relationship between early postoperative complications after radical cystectomy and preoperative PMI in elderly male patients.The right renal artery has been considered to originate laterally from the anterior aspect of aorta. In some cases, it turns more ventrally than the aorta, which can lead to intraoperative right renal artery injury. For this reason, we evaluated how the right renal artery turns ventrally and analyzed the factors for ventral protrusion of the right renal artery. We examined contrast-enhanced computed tomography images of 195 individuals and measured their angles of the right renal artery and ventral protrusion from the aorta. Age and sex had no significant correlation with these variations. A weaknegative correlation was found between body mass index and these variations. Almost all the right renal artery originated from the ventral side of the aorta, and almost half the right renal artery arose ventrally more than the aorta. Careful attention should be paid to ventral protrusion of the right renal artery to prevent vascular injury during surgery using the anterior approach to the upper retroperitoneum.
