Gastric cancer with positive peritoneal cytology: survival benefit after induction chemotherapy and conversion to negative peritoneal cytology. World J Surg Oncol 2021; 19:245. [PMID: 34404403 PMCID: PMC8371873 DOI: 10.1186/s12957-021-02351-x] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 07/27/2021] [Indexed: 12/16/2022] Open
Abstract
Background The optimal treatment in patients with gastric cancer and peritoneal disease remains controversial. Some guidelines indicate palliative treatment only, while others consider surgical treatment in case of positive lavage cytology (CY+) or limited peritoneal disease. Here, we analyzed the role of peritoneal disease in patients with gastric cancer, and the prognostic relevance of response to neoadjuvant therapy. Methods In this retrospective cohort analysis, we analyzed patients with adenocarcinoma of the stomach or esophago-gastric junction from a single center operated between 2011 and 2019. According to histology and lavage cytology, patients were classified into four risk groups: (A) no peritoneal disease, (B) CY+ who converted to negative lavage cytology (CY−) after neoadjuvant chemotherapy, (C) CY+ without conversion after chemotherapy, and (D) patients with visible peritoneal metastasis. Results Overall, n = 172 patients were included. At initial presentation, n = 125 (73%) had no peritoneal disease, and about a third of patients (n = 47, 27%) had microscopic or macroscopic peritoneal disease. Among them, n = 14 (8%) were CY+ without visible peritoneal metastasis, n = 9 converted to CY− after chemotherapy, and in n = 5 no conversion was observed. Median overall survival was not reached in patients who had initially no peritoneal disease and in patients who converted after chemotherapy, resulting in 3-year survival rates of 65% and 53%. In contrast, median overall survival was reduced to 13 months (95% CI 8.7–16.7) in patients without conversion and was 16 months (95% CI 12–20.5) in patients with peritoneal metastasis without difference between the two groups (p = .364). The conversion rate from CY+ to CY− was significantly higher after neoadjuvant treatment with FLOT (5-fluorouracil plus leucovorin, oxaliplatin, and docetaxel) compared to ECF (epirubicin, cisplatin, and 5-fluorouracil) (p = 0.027). Conclusion Conversion of CY+ to CY− after neoadjuvant chemotherapy with FLOT is a significant prognostic factor for a better overall survival. Surgical treatment in well-selected patients should therefore be considered. However, peritoneal recurrence remains frequent despite conversion, urging for a better local control.

Abstract
Precision medicine is a medical approach to administer patients with a tailored dose of treatment by taking into consideration a person's variability in genes, environment, and lifestyles. The accumulation of omics big sequence data led to the development of various genetic databases on which clinical stratification of high-risk populations may be conducted. In addition, because cancers are generally caused by tumor-specific mutations, large-scale systematic identification of single nucleotide polymorphisms (SNPs) in various tumors has propelled significant progress of tailored treatments of tumors (i.e., precision oncology). Machine learning (ML), a subfield of artificial intelligence in which computers learn through experience, has a great potential to be used in precision oncology chiefly to help physicians make diagnostic decisions based on tumor images. A promising venue of ML in precision oncology is the integration of all available data from images to multi-omics big data for the holistic care of patients and high-risk healthy subjects. In this review, we provide a focused overview of precision oncology and ML with attention to breast cancer and glioma as well as the Bayesian networks that have the flexibility and the ability to work with incomplete information. We also introduce some state-of-the-art attempts to use and incorporate ML and genetic information in precision oncology.

Abstract
The cytology of peritoneal washing fluids for gastric cancer is the most basic method for judging peritoneal micrometastasis. However, the clinical value of this method is not clear at present. A retrospective analysis was performed on 277 patients with pathologically proven and surgically treated gastric cancer. The peritoneal washing fluids were collected after opening the abdomen and before the operation, and were sent to the cytology laboratory for screening of occult cancer cells in the collected washing fluids. The number of cases diagnosed as cancer cells, reactive mesothelial cells, serosal balls, and traumatic mesothelial cells were 42, 18, 27, and 190, respectively. Typical adenocarcinoma cell nests were found in eight of 10 T4b samples, whereas 34 cases of cancer cells in T3 and T4a showed that these cell nests usually contained mesothelial cells, and the three-dimensional stereoscopic sense of the nests was not obvious. In the specific subcellular morphological changes of both reactive mesothelial cells and serosal balls, the changes of both the contour of nuclear membrane and the polarity of cell alignment were present only in stage T3 and T4a. The presence or absence of mesothelial cells in the nests of cancer cells and the changes of the contour of nuclear membrane and of the polarity of cell alignment in reactive mesothelial cells or serosal balls may help us to predict the depth of invasion of cancer cells.

Abstract
BACKGROUND Peritoneal cytology has been used as a part of the cancer staging of gastric cancer patients. The primary aim of this systematic review was to evaluate the value of peritoneal cytology as part of the staging of gastric cancer and survival prediction. The second aim was to establish if positive cytology may be modified by neoadjuvant therapy, to improve prognosis. METHODS An electronic literature search was performed using Embase, Medline, Web of Science, and Cochrane library databases up to January 2016. The logarithm of the hazard ratio (HR) with 95% confidence intervals (CI) was used as the primary summary statistic. Comparative studies were used, and the outcome measure was survival in three groups: (1) positive versus negative cytology at staging laparoscopy immediately preceding surgery; (2) effect of neoadjuvant therapy on cytology and survival; and (3) positive cytology in the absence of macroscopic peritoneal disease was compared with obvious macroscopic peritoneal disease. RESULTS Pooled analysis demonstrated that positive cytology was associated with significantly reduced overall survival (HR, 3.46; 95% CI, 2.77-4.31; P < 0.0001). Interestingly, negative cytology following neoadjuvant chemotherapy was associated with significantly improved overall survival (HR, 0.42; 95% CI, 0.31-0.57; P < 0.0001). The absence of macroscopic peritoneal disease with positive cytology was associated with significantly improved overall survival (HR, 0.64; 95% CI, 0.56-0.73; P < 0.0001). CONCLUSION This study suggests that patients with initial positive cytology may have a good prognosis following neoadjuvant treatment if the cytology results change to negative after treatment.

Abstract
Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze intraperitoneal free cancer cells-positive patients with regard to tumor oncologic stage, recurrence, grade of cellular differentiation, and survival rates and to analyze the clinical significance of intraperitoneal free cancer cells with regard to prognosis. Databases were searched up to January 2016 for prognostic factors associated with intraperitoneal free cancer cells, including oncologic stage, depth of neoplasm invasion, lymph nodal spread, differentiation grade of the tumor, and recurrence and survival rates. A total of 100 studies were identified. Meta-analysis revealed a clear association between intraperitoneal free cancer cells and a poor prognosis. intraperitoneal free cancer cells -positive patients had higher rates of nodal spread (risk difference: 0.29; p<0.01), serosal invasion (risk difference: 0.43; p<0.01), recurrence (after 60 months of follow-up, risk difference: 0.44; p<0.01), and mortality (after 60 months of follow-up, risk difference: 0.34; p<0.01). Intraperitoneal free cancer cells are associated with a poor outcome in gastric cancer. This surrogate biomarker should be used to guide therapy both prior to and after surgery.

Abstract
OBJECTIVE To evaluate the diagnostic value of cytological greater omental milky spot examination for the diagnosis of peritoneal metastasis in gastric cancer patients. METHODS A total of 136 patients diagnosed with gastric cancer and without distant metastasis were enrolled in our study. All patients underwent laparoscopy and CH40 suspension liquid dye of peritoneal lymph nodes preoperatively as well as ascites or peritoneal lavage fluid collections and excisions of marked greater omental milky spot tissues perioperatively. RESULTS According to the laparoscopic results, the patients were divided into T1-T2 stage (n = 56) without and into T3-T4 stage (n = 80) with tumor invasion into the serosal layer. Among the T1-T2-stage patients, tumor cells could be detected in peritoneal lavage fluids in 2 cases, whereas with greater omental milky spot examination, peritoneal metastasis was detected in 8 cases. Among the 80 cases in the T3-T4 stage, tumor cells could be detected in 28 cases via peritoneal lavage cytology and in 43 cases by greater omental milky spot examinations, and 4 cases had cancer cell infiltration also in nonmilky spot omental areas. The statistical analysis showed that the staging accuracy rate of exfoliative cytology examination was superior to that of the laparoscopic exploration (P < .05), but its sensitivity was significantly lower than that obtained with cytological greater omental milky spot examinations (P < .05). CONCLUSIONS The laparoscopic exploration could make a preliminary diagnosis of peritoneal metastasis via serosal layer invasion detection. For further analyses, cytological examinations of greater omental milky spots were more sensitive than exfoliative cytology.

Abstract
Peritoneal carcinomatosis appears to be the most common pattern of metastasis or recurrence and is associated with poor prognosis in gastric cancer patients. Many efforts have been made to improve the survival in patients with peritoneal metastasis. Hyperthermic intraperitoneal chemotherapy remains a widely accepted strategy in the treatment of peritoneal dissemination. Several phase II-III studies confirmed that the combined cytoreducitve surgery and hyperthermic intraperitoneal chemotherapy resulted in longer survival in patients with peritoneal carcinomatosis. In addition, proper selection and effective regional treatment in patients with high risk of peritoneal recurrence after resection will further improve prognosis in local advanced gastric cancer patients.

Abstract
PURPOSE Despite continuously improving therapies, gastric cancer still shows poor survival in locally advanced stages with local recurrence rates of up to 50% and peritoneal recurrence rates of 17% after curative surgery. We performed a systematic review with meta-analyses to clarify whether positive intraperitoneal cytology (IPC) indicates a high risk of disease recurrence and poor overall survival in gastric cancer. METHODS Multiple databases were searched in December 2014 to identify studies on the prognostic significance of positive intraperitoneal cytology in gastric cancer, including: Medline, Biosis, Science Citation Index, Embase, CCMed and publisher databases. Hazard ratios (HR) and associated 95% confidence intervals (CI) were extracted from the identified studies. A meta-analysis was performed using a random-effects model on overall survival, disease-free survival and peritoneal recurrence free survival. RESULTS A total of 64 studies with a cumulative sample size of 12,883 patients were included. Cytology, quantitative real time polymerase chain reaction (PCR) or both were performed in 35; 21 and 8 studies, respectively. Meta analyses revealed free intraperitoneal tumor cells (FITC) to be associated with poor overall survival in univariate (HR 3.27; 95% CI 2.82 - 3.78]) and multivariate (HR 2.45; 95% CI 2.04 - 2.94) analysis and poor peritoneal recurrence free survival in univariate (4.15; 95% CI 3.10 - 5.57) and multivariate (3.09; 95% CI 2.02 - 4.71) analysis. Subgroup analysis showed this effect to be independent of the detection method, Western or Asian origin or the time of publication. CONCLUSIONS FITC oder positive peritoneal cytology is associated with poor survival and increased peritoneal recurrence in gastric cancer.

Abstract
To investigate whether the width of gastric serosal lesions in advanced gastric cancer patients have a predictive value for peritoneal recurrence and the 5-year survival rate.A total of 1109 patients with advanced noncardia primary gastric adenocarcinoma, who underwent curative gastrectomy between January 1997 and December 2007, were included. Data about tumor size, longitudinal tumor location, resection type, serum albumin concentration, lymphatic/venous invasion, lymph node metastasis status, lesion size, histological and Borrmann type of tumor, as well as the recurrence rate and width of the gastric serosal lesions were collected and analyzed.The peritoneal recurrence rate in patients with gastric serosal lesions ≤3 cm was lower than in patients with gastric serosal lesions >3 cm. Multivariate analyses of the 5-year survival rate variables for all patients revealed significant correlations with serum albumin concentrations (HR 1.382, P = 0.002, 95% CI 1.123-1.701), width of serosa changes (HR 1.377, P = 0.020, 95% CI 1.053-1.802), depth of invasion (HR 1.529, P < 0.001, 95% CI 1.288-1.814), and lymph node metastasis (HR 1.551, P < 0.001, 95% CI 1.420-1.694), whereas for recurrent patients only serum albumin concentrations (HR 2.000, P < 0.001, 95% CI 1.425-2.805), width of serosa changes (HR 1.867, P = 0.002, 95% CI 1.248-2.793), and lymph node metastasis (HR 1.521, P < 0.001, 95% CI 1.249-1.852) correlated with the 5-year survival rate.Gastric serosal lesions >3 cm may indicate a high risk for peritoneal recurrence and serve as additional indicators for preventive postoperative adjuvant chemotherapies in patients with advanced gastric cancer.

Abstract
Recently, a novel comprehensive treatment consisting of cytoreductive surgery (CRS) and perioperative chemotherapy (POC) was developed for the treatment of peritoneal metastasis (PM) with a curative intent. In the treatment, the macroscopic disease is completely removed by the peritonectomy techniques in combination with POC. This article reviews the results of the comprehensive treatment for PM from gastric cancer, and verifies the effects of CRS and POC, including neoadjuvant chemotherapy (NAC) and hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC). Completeness of cytoreduction, peritoneal carcinomatosis index (PCI) less than the threshold levels after NAC, absence of ascites, cytologic status, pathologic response after NAC are the independent prognostic factors. Among these prognostic factors, PCI threshold level is the most valuable independent prognostic factor. After staging laparoscopy, patients with PM from gastric cancer are recommended to treat with NAC before CRS. After NAC, indication for CRS is determined by laparoscopy. The indications of the comprehensive treatment are patients with PCI less than the threshold levels, negative cytology, and responders after NAC. Patients satisfy these factors are the candidates for the CRS and HIPEC.
