Important Predictive Factors for the Prognosis of Patients With Peritoneal Metastasis of Gastric Cancer.

BACKGROUND: This study investigated predictive factors for patients with peritoneal metastases of gastric cancer (PMGC) who underwent conversion cytoreductive surgery (C-CRS) and hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC) after responding to induction chemotherapy (laparoscopic HIPEC [LHIPEC]) followed by concomitant systemic and intraperitoneal chemotherapy (bidirectional intraperitoneal and systemic chemotherapy [BIC]). METHODS: Diagnostic laparoscopy was performed for 62 patients with PMGC between January 2017 and December 2022. The patients underwent LHIPEC and BIC induction chemotherapy using intraperitoneal docetaxel (30 mg/m2) and cisplatin (30 mg/m2), and intravenous chemotherapy for three cycles. The predictive parameters for progression-free and overall survival were analyzed using Kaplan-Meier and Cox regression analyses. The optimal cutoff values for Ki-67 parameters were assessed using receiver operating characteristic curve analysis. RESULTS: The study retrospectively examined 36 (58 %) of 62 patients who responded to induction therapy and underwent C-CRS or HIPEC. A Ki-67 index lower than 10 (p = 0.000), lymph node involvement (LNI) less than 2 (p = 0.039), and an omental lesion size score lower than 0.5 cm (p = 0.002) were predictive of recurrence-free and overall survival in addition to completeness of cytoreduction and the peritoneal cancer index. Cox regression analysis showed that the independent factors associated with recurrence-free survival were decreased Ki-67 expression (≥10 % vs <10 %) (hazard ratio [HR] 4.7; 95 % confidence interval [CI] 1.6-5.210; p = 0.020) and LNI higher than 2 (HR 1.92; 95% CIS 0.923-4.0; p = 0.023). CONCLUSIONS: Lymph node involvement and decreased Ki-67 expression are independent predictive factors of recurrence-free survival for patients with PMGC after induction chemotherapy.

Is there no need to discuss adjuvant chemotherapy in stage II colon cancer patients with high tumor budding and lymphovascular invasion?

PURPOSE: The aim of this study is to evaluate the clinicopathologic associations of tumor budding (Bd) as well as other potential prognosticators including lymphovascular invasion (LVI) in T3/4aN0 colon cancer patients and to investigate their impact on the outcome. METHODS: The patients were enrolled in three groups according to the number of budding as Bd1 (0-4 buds), Bd2 (5-9 buds), and Bd3 (> 10 buds). These groups were retrospectively compared in terms of demographic features, other tumor characteristics, operative outcomes, recurrences, and survival. The mean follow-up time was 58 ± 22 months. RESULTS: A total of 194 patients were divided as follows: 97 in Bd1, 41 in Bd2, and 56 in Bd3 groups. The Bd3 group was associated with significantly higher LVI and larger tumor size. The rate of recurrence increased progressively from 5.2% in Bd1 to 9.8% in Bd2 and to 17.9% in Bd3 group (p = 0.03). More importantly, the 5-year overall survival (OS: Bd1 = 92.3% vs. Bd2 = 88% vs. Bd3 = 69.5%, p = 0.03) and disease-free survival (DFS: Bd1 = 87.9% vs. Bd2 = 75.3% vs. Bd3 = 66%, p = 0.02) were significantly worse in Bd3 group. In addition, in the subgroup of patients with the presence of Bd3 and LVI together, the 5-year OS (60% vs. 92%, p = 0.001) and DFS (56.1% vs. 85.4%, p = 0.001) were significantly worse. In multivariate analysis, Bd3+LVI was significantly associated with poor OS and DFS (p < 0.001). CONCLUSION: In patients with T3/4aN0 colon cancer, high tumor budding negatively affects long-term oncological outcomes. These findings strongly suggest that adjuvant chemotherapy be considered for the patients with Bd3 and LVI together.

Preoperative Stress: An Operating Room Nurse Intervention Assessment.

PURPOSE: The purpose of this research study was to determine the effect of preoperative visits by the operating room (OR) nurse on patient stress levels before undergoing surgery. DESIGN: This research was a quasi-experimental study. METHODS: The research sample included patients (N = 179) who were hospitalized for surgery during 6 months in the general surgery department of a public hospital in the Eastern Black Sea Region. The OR nurse, part of the medical staff for surgery, visited patients in the experimental group 1 day before surgery. The OR nurse collected information that was consistent with the requirements of the patients. Patients in the control group were provided with preoperative care that was consistent with hospital procedure. Research data were collected using question forms, patient satisfaction scores, and Burford Distress Thermometer scale. Statistical evaluations included t tests and receiver operating characteristic analysis for independent groups. FINDING: Most patients stated that they felt stressed because of the impending surgery. Patients made the following most common statements of the factors that caused stress; fear of unknown, anesthesia phobia, and fear of OR environment and complications that may occur during surgery. Patients in both groups experienced a significant decrease in postoperative stress levels. The perceived distress in the experimental group was significantly lower than the control group during the postoperative period. Patients in the experimental group reported that the OR nurse's visit effectively minimized their stress levels. CONCLUSIONS: OR nurse visits to patients before surgery contributed to decreased preoperative stress levels.

Intra-ampullary Papillary Tubular Neoplasm (IAPN): Clinicopathologic Analysis of 72 Cases Highlights the Distinctive Characteristics of a Poorly Recognized Entity.

The guidelines recently recognized the intra-ampullary papillary tubular neoplasm (IAPN) as a distinct tumor entity. However, the data on IAPN and its distinction from other ampullary tumors remain limited. A detailed clinicopathologic analysis of 72 previously unpublished IAPNs was performed. The patients were: male/female=1.8; mean age=67 years (range: 42 to 86 y); mean size=2.3 cm. Gross-microscopic correlation was crucial. From the duodenal perspective, the ampulla was typically raised symmetrically, with a patulous orifice, and was otherwise covered by stretched normal duodenal mucosa. However, in 6 cases, the protrusion of the intra-ampullary tumor to the duodenal surface gave the impression of an "ampullary-duodenal tumor," with the accurate diagnosis of IAPN established only by microscopic correlation illustrating the abrupt ending of the lesion at the edge of the ampulla. Microscopically, the preinvasive component often revealed mixed phenotypes (44.4% predominantly nonintestinal). The invasion was common (94%), typically small (mean=1.2 cm), primarily pancreatobiliary-type (75%), and showed aggressive features (lymphovascular invasion in 66%, perineural invasion in 41%, high budding in 30%). In 6 cases, the preinvasive component was pure intestinal, but the invasive component was pancreatobiliary. LN metastasis was identified in 42% (32% in ≤1 cm IAPNs). The prognosis was significantly better than ampullary-ductal carcinomas (median: 69 vs. 41 months; 3-year: 68% vs. 55%; and 5-year: 51% vs. 35%, P=0.047). Unlike ampullary-duodenal carcinomas, IAPNs are often (44.4%) predominantly nonintestinal and commonly (94%) invasive, displaying aggressive features and LN metastasis even when minimally invasive, all of which render them less amenable to ampullectomy. However, their prognosis is still better than that of the "ampullary-ductal" carcinomas, with which IAPNs are currently grouped in CAP protocols (while IAPNs are kindreds of intraductal tumors of the pancreatobiliary tract, the latter represents the ampullary counterpart of pancreatic adenocarcinoma/cholangiocarcinoma).

Individuals' Coping Styles and Levels of Depression, Anxiety, and Stress During the COVID-19 Pandemic in Turkey: A Web-Based Cross-Sectional Study.

This cross-sectional study aimed to determine the correlation between the coping styles and depression, anxiety, and stress levels of individuals living in Turkey during the COVID-19 pandemic. The study was conducted using an online questionnaire (Socio-demographic Form; Depression, Anxiety, and Stress Scale-21; Coping Styles Scale) and it included 483 individuals. Descriptive statistics, ANOVA, Independent Samples t-test, Kolmogorov-Smirnov, Hosmer-Lemeshow and Scheffe tests, Pearson Correlation, and Binary Logistic Regression analyzes were used to analyze the data. There was a negative correlation between the participants' self-confident and optimistic coping styles mean scores and their depression, anxiety, and stress mean scores. There was a positive correlation between the participants' helpless, submissive, and seeking social support coping styles mean scores and their depression, anxiety, and stress mean scores. The regression analysis revealed that using the helpless coping style increased the depression, anxiety, and stress levels of the participants while using the optimistic coping style and visiting a physician during the pandemic decreased them. In addition, seeking social support coping style increased the level of depression while the testing during the pandemic increased stress levels. As a result, it is recommended to strengthen society's psychological resilience and expand mental health support services for such mental illnesses.

Omental calcified fibrous tumor with symptoms after COVID-19 infection.

Calcified fibrous tumor (CFT) is a rare benign tumor of mesenchymal origin. Between 1988 and 2019, a total of 272 CFT cases were reported. CFTs can be seen in all anatomical regions with soft tissue. Histologically, mononuclear inflammatory infiltrates and the presence of psammomatous calcification in dense hyalinized collagen are characteristic features of the tumor. Currently, if the tumor is located in only one focus, surgical removal is recommended. Although CFT is a benign tumor, it may cause complications. Diagnosis is often difficult due to the confusion of tumor findings with many diseases. We present a patient with CFT, whose omental lesions were detected on abdominal computed tomography, and the diagnosis was confirmed by histopathological examination.

Transrectal ultrasound guided multi-core prostate biopsy: pain control: results of 106 patients.

PURPOSE: To determine the efficacy of periprostatic nerve block (PPNB) for control of transrectal ultrasound (TRUS)-guided multicore prostate biopsy-related pain. METHODS: A total of 106 cases with suspicion of prostate cancer underwent TRUS-guided multicore prostate biopsy under local anesthesia using a total of 10 ml of 1% lidocaine for each patient. Lidocaine was injected around the neurovascular bundle at the base of the prostate just lateral to the seminal vesicle-prostate junction. The pain score was assessed using visual analog pain score from 0 to 10. All patients were questioned for whether they would accept repeat biopsy or not, if necessary. RESULTS: Pain score ranged from 0 to 5 (mean: 1.4). Thirty-five percent (37/106) of patients reported a score of 0, whereas 17% (18/106), 32% (34/106), 8.4% (9/106), 6.7% (7/106), 0.9% (1/106) reported pain scores of 1, 2, 3, 4, and 5, respectively. There were no pain scores of 6-10. Answers for the question "would you accept repeat biopsy or not, if necessary?" was "yes" for 82% (87/106) of the patients. CONCLUSIONS: PPNB prior to multi-core TRUS-guided prostate biopsy is an easy, safe, and effective technique for the control of procedure-related pain.

Surgery with hyperthermic intraperitoneal chemotherapy after response to induction chemotherapy in patients with peritoneal metastasis of gastric cancer.

BACKGROUND: Gastric cancer (GC) with peritoneal metastases (PM) has a dismal prognosis and to date only a few management options have been reported. Of those, cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) after induction bidirectional intraperitoneal and systemic chemotherapy (BIPSC) appear as a promising treatment option for these patients. Outcome data including safety and efficacy of CRS with radical Gastrectomy and HIPEC after response to combination of laparoscopic HIPEC (LHIPEC) with BIPSC as an induction therapy in patients with PM of GC was evaluated in this retrospective observational study. METHODS: Diagnostic Laparoscopy was performed in 53 patients with PM of GC who admitted to the Center for Treatment of Peritoneal Surface Malignancies, Istanbul, between 2013 and 2016. Peritoneal cancer index (PCI), ascites status and cytology were determined. The patients underwent LHIPEC and then, BIPSC induction chemotherapy using intraperitoneal docetaxel (30 mg/m2) and cisplatin (30 mg/m2) and intravenous Docetaxel/Cisplatin/5-Fluorouracil (DCF) for 3 cycles. In selected patients, CRS with radical gastrectomy and HIPEC were performed after the response to induction therapy. BIPSC was continued for 3 more cycles with a dose reduction in an adjuvant setting. RESULTS: All LHIPEC procedures were uneventful with Grade 1-2 side effects (11/53, 20,8%). As a response to induction chemotherapy PCI was reduced from 19.6±8 (range, 6-39) to 13.6±9.8 (range, 1-39) (P<0.001). Ascites was detected in 55% (29 out of 53) and cytology was positive in 51% (27 out of 53) of the patients before induction chemotherapy. Ascites was completely abolished and all cytology became negative. Then, 34 of 53 (64.15%) patients underwent CRS with radical gastrectomy and HIPEC. CC0/1 resection was achieved in 22 (64.70%) of patients (P<0.05). The median survival time was 18.9±13.4 (95% CI: 15.2-22.6 months. Combined surgery and HIPEC related mortality occurred in 1 out of 34 patients (2.9%) due to developed diffuse intravascular coagulation at postoperative day 2. Grade 2 operative complications included biliary fistula in one, and duodenal stump leakage in two patients (8.7%). All of the fistula closed with conservative management. The median survival time was 18.9±13.4 months and the median progression-free survival time was 15.6±12.9 with 1-, 2-, and 5-year survival rates of 82.4%, 59% and 17.6% in patients with PM of GC. Multivariate analysis identified high peritoneal cancer index (P=0.000) and complete resection (P<0.05) as independent predictors for better progression-free and overall survival. CONCLUSIONS: The best outcomes can be expected with optimal cytoreduction and limited peritoneal dissemination in response to induction chemotherapy. Knowledgeable selection of patients with PM of GC is essential to perform surgery with HIPEC safely with acceptable mortality and morbidity.

Pathologic Evaluation of Large Colorectal Endoscopic Submucosal Dissections: An Analysis of 279 Cases With Emphasis on the Importance of Multidisciplinary Work and Establishing Examination Protocols.

Background. Endoscopic submucosal dissections (ESDs) allow removal of large gastrointestinal tumors and help patients avoid major oncologic surgery. In this study, the challenges and development of approaches toward successfully handling ESDs were analyzed in 279 colorectal specimens (114 rectal, 47 left, 118 right colonic; 90% adenoma with/without carcinoma). Methods. Each specimen was processed according to an established protocol including gross photography, mapping, and total submission for histopathologic examination. Results. Mean lesion size was 4.2 cm (range: 0.5-22 cm; 28% ≥5 cm; 6% ≥10 cm). Invasive carcinoma was present in 38 cases (14%), which had a mean overall tumor size of 3.8 cm (range: 1.1-17.5 cm), and mean largest size of the invasive component was 0.93 cm (range: 0.04-3 cm). Fifteen cases were staged as pT1a (submucosal invasion of <1000 µm) and 13 cases as pT1b (submucosal invasion of ≥1000 µm). En-bloc and R0 resection rates were 99.3% and 90.6%, respectively. Conclusion. Various histopathologic challenges were encountered, which were carefully evaluated by dedicated pathologists with familiarity to the subtleties in handling and reporting these specimens. We recommend these specimens to be prepared in the endoscopy suite, submitted to the Pathology Department oriented, pinned, and placed into copious amount of fixative. Total sampling, gross photography, mapping, and proper fixation are crucial components in the histopathologic evaluation. Micromeasurement of invasion depth and substaging per European/Japanese guidelines as well as accurate measurement of the distance from the resection margins are highly recommended. In conclusion, ESD is an adequate method that can be successfully implemented in a tertiary care center to perform en-bloc and margin-free resections of clinically selected large colorectal superficial lesions.
