Background
The use of staging laparoscopy (SL) has become widespread in patients with advanced gastric cancer (GC). This study aimed to evaluate the predictive value of the neutrophil/lymphocyte ratio (NLR) for the presence of peritoneal metastasis during staging laparoscopy in patients with advanced GC.
Methods
This retrospective analysis was performed in 35 patients with advanced GC who underwent SL at Kanazawa Medical University Hospital between January 2009 and December 2017. Clinicopathological characteristics were examined and multivariate analyses were performed to identify preoperative laboratory parameters that were independently associated with the presence of peritoneal metastasis or cytological malignancy (P/CY positive) during SL.
Results
A P/CY-positive result was confirmed during SL in 16 patients (45.7%). Patients with type 4 or diffuse type 3 tumors showed a significantly higher P/CY-positive rate than those with other tumor types (58.3% vs. 18.2%,
P
= 0.02). In the univariate analysis for preoperative laboratory parameters, NLR (
P
< 0.0001) and total protein (
P
= 0.03) and albumin (
P
= 0.04) levels were significantly correlated with a P/CY-positive result. On multivariate analysis, NLR was significantly correlated with a P/CY-positive result (
P
= 0.0002). In patients with type 4 or diffuse type 3 tumors, a high NLR (> 3.5) was associated with a significantly higher P/CY-positive rate than a low NLR (≤ 3.5) (83.3% vs. 33.3%,
P
= 0.01). Moreover, in patients without type 4 or diffuse type 3 tumors, the P/CY-positive rates were 100% and 0% in patients with NLR > 3.5 and NLR ≤ 3.5, respectively.
Conclusions
The preoperative NLR was a significant independent predictor of the presence of peritoneal metastasis during SL. Regardless of tumor type, patients with a high NLR could be reasonable candidates for SL. On the other hand, non-diffuse type tumor accompanied by a low NLR may not need to undergo SL.
The purpose of this study was to retrospectively evaluate brachytherapy for early stage squamous cell carcinoma of the oropharynx (SCO) in relation to second primary respiratory and upper digestive tract cancers (RUDT). Between 1976 and 2001, 111 previously untreated patients with stage I or II SCO were treated with Au-198 seed brachytherapy alone (36 cases) or Au-198 seed brachytherapy plus external irradiation (75 cases). Of the 111 patients, 28 patients had stage I disease and 83 patients had stage II disease. Each patient was evaluated for therapeutic efficacy, post-treatment quality of life (QOL) and a second cancer. The 5-year and 10-year cause-specific actuarial survival rates for stage I and II SCO were 87% and 86%, respectively. We found that the 5-year and 10-year survival rates for all SCOs combined with second primary RUDT cancers were 71% and 45%, respectively. 51 second primary RUDT cancers occurred successively in 41 patients following treatment for early stage oropharyngeal cancer and this was the sole prognostic factor by the multivariate analysis. Au-198 seed brachytherapy with or without ipsilateral external irradiation of up to 30 Gy was associated with fewer late complications in the oral cavity and salivary gland. We concluded that our treatment policy of brachytherapy with or without external irradiation for patients with early stage SCO was effective and acceptable from the standpoint of tumour control and post-treatment QOL.
Background/Aim: We evaluated whether splenic volume (SV) predicts sinusoidal obstruction syndrome (SOS) in colorectal cancer (CRC) patients receiving capecitabine plus oxaliplatin (CapeOX) therapy. Patients and Methods: In this retrospective study, we measured SV in 41 patients receiving adjuvant CapeOX for CRC at five different time points. We compared the clinical data of the 18 patients who experienced ≥30% increases in SV immediately after vs. before CapeOX (group A) with data for the remaining 23 patients (group B). Results: Platelet numbers decreased and the levels of hepatobiliary enzymes increased significantly 1 year after CapeOX compared with before CapeOX in group A. However, in group B, significantly decreased platelet numbers and significantly increased aspartate transaminase levels were confirmed only immediately after CapeOX, with no significant subsequent changes. Conclusion: SV was significantly associated with thrombocytopenia and liver dysfunction in CRC patients, and predicted SOS.
A 48-year-old woman was admitted to our hospital because of upper abdominal pain. Computer tomography showed an enhancing mass in the pancreatic body, dilation of the main pancreatic duct (MPD) and a filling defect within the splenic vein. On the basis of the preoperative diagnosis of pancreatic body cancer, distal pancreatectomy was scheduled. The pancreas was divided along the left edge of the gastroduodenal artery; however, frozen pathological examination of the pancreatic stump was tumor positive, and therefore a total pancreatectomy was performed. The lesion was a white expansive nodular mass that had spread into the MPD and protruded into the splenic vein. A pathological diagnosis of non-functioning neuroendocrine tumor (NET) was made. In general, imaging findings of disruption of the MPD and tumor vein thrombus are characteristics of pancreatic ductal adenocarcinoma, but are uncommon in NET. However, NET should be included in the differential diagnosis for such patients.
