Abstract
The selection of appropriate treatment modalities based on the presence or absence of mutations in KRAS, NRAS, BRAF, and the microsatellite instability (MSI) status has become a crucial consensus in colorectal cancer (CRC) therapy. However, the distribution pattern of these genetic mutations and the prevalence of MSI status in Chinese stage I-III CRCs remain unclear. We retrospectively analyzed clinicopathological features, mutations in the KRAS, NRAS, and BRAF genes, as well as MSI status of 411 patients with stage I-III CRC who underwent surgery from June 2020 to December 2022 in the First Affiliated Hospital of Nanjing Medical University. The mutation rates of KRAS, NRAS, and BRAF were 48.9%, 2.2%, and 3.2%, respectively, and the microsatellite instability-high rate was 9.5%. KRAS mutation was independently associated with mucinous adenocarcinoma. Multivariate analysis suggested that tumor location and mucinous adenocarcinoma were independently associated with BRAF mutation. Only T stage was associated with NRAS mutations in the univariate analysis. Multivariate analysis revealed that factors such as larger tumor size, tumor location, younger age, and poor differentiation were independently associated with microsatellite instability-high status. The results illustrate the mutation frequencies of KRAS, NRAS, BRAF genes and MSI status in stage I-III CRC from the eastern region of China. These findings further validate the associations between these genes status and various clinicopathological characteristics.

Abstract
Keratan sulfate glycosaminoglycan is composed of repeating N-acetyllactosamine (LacNAc) disaccharide units consisting of galactose (Gal) and N-acetylglucosamine (GlcNAc), both often 6-O-sulfated. Sulfate contents of keratan sulfate are heterogeneous depending upon the origins. In this study, keratan sulfate is classified as either highly sulfated (in which both GlcNAc and Gal residues are 6-O-sulfated) or low-sulfated (in which only GlcNAc residues are 6-O-sulfated). It is reported that highly sulfated keratan sulfate detected by the 5D4 monoclonal antibody is preferentially expressed in normal epithelial cells lining the female genital tract and in their neoplastic counterparts; however, expression of low-sulfated keratan sulfate in either has not been characterized. In the present study, we generated the 294-1B1 monoclonal antibody, which selectively recognizes low-sulfated keratan sulfate, and performed precise glycan analysis of sulfated glycans expressed on human serous ovarian carcinoma OVCAR-3 cells. We found that OVCAR-3 cells do not express highly sulfated keratan sulfate but rather express low-sulfated form, which was heterogeneous in 294-1B1 reactivity. Comparison of mass spectrometry spectra of sulfated glycans in 294-1B1-positive versus -negative OVCAR-3 cells indicated that the 294-1B1 epitope is likely at least 2, and possibly 3 or more, tandem GlcNAc-6-O-sulfated LacNAc units. Then, using the 294-1B1 antibody, we performed quantitative immunohistochemical analysis of 40 specimens from patients with ovarian cancer, consisting of 10 each of serous, endometrioid, clear cell, and mucinous carcinomas, and found that among them low-sulfated keratan sulfate was widely expressed in all but mucinous ovarian carcinoma.

Abstract
Primary vulvar adenocarcinoma is a particularly rare tumor with poorly understood histogenesis and unclear clinical characteristics and prognosis. Vulvar adenocarcinoma of intestinal type (VAIt) is a very uncommon subtype of primary vulvar adenocarcinoma and only 27 cases have been described in the literature in the past. Of these cases, two have been described as human papillomavirus (HPV)-associated VAIt. The current report presents two additional cases of primary VAIt showing variants in the KRAS, TP53, and DPYD genes and no evidence of HPV DNA by real-time polymerase chain reaction (RT-PCR). Next-generation sequencing (NGS) revealed TP53 pathogenic variants in both cases, but only one case had aberrant p53 protein immunohistochemical characteristics. KRAS and DPYD mutations were identified separately in the two cases. Due to their capacity to imitate the spread of more prevalent gastrointestinal carcinomas, these tumors may present diagnostic issues. Additional cases can contribute to a better understanding of the pathophysiology and prognosis of VAIt.

Abstract
OBJECTIVE To determine the predictive factors for the pathological complete response (pCR) in patients with non-ductal invasive breast cancer (ND-BC) receiving neoadjuvant chemotherapy. STUDY DESIGN Observational study. Place and Duration of the Study: Departments of Medical Oncology, Tekirdag Namik Kemal University, Sirnak State Hospital, Aydin Adnan Menderes University, Marmara University, Bakirkoy Sadi Konuk Hospital, Basaksehir Cam and Sakura Hospital, Sakarya University, Balıkesir Ataturk Hospital, Turkiye, from April 2016 to December 2022. METHODOLOGY A total of 222 non-metastatic breast cancer patients who received neoadjuvant chemotherapy were included in this retrospective multicentric study. The clinicopathologic data were obtained from the hospitals' electronic-record-system. The logistic regression models were used to identify predictive factors for pCR. RESULTS One hundred and twenty-six patients (56.8%) had invasive lobular carcinoma and 28 patients (12.6%) had signet ring cell/mucinous carcinoma. A total of 45 patients (20.3%) achieved pCR. The pCR rate was 14.3% for lobular carcinoma and 17.9% for signet ring cell/mucinous carcinoma. The univariate analysis showed that estrogen receptor-negative tumours (p = 0.017), high Ki-67 (p = 0.008), high histologic grade (p<0.001), HER2+ expression (p<0.001), and non-lobular histologic type (p = 0.012) were predictive factors for pCR. The multivariate model revealed that HER2 expression (p<0.001) and Ki-67 (p = 0.005) were independent predictors. CONCLUSION Neoadjuvant chemotherapy demonstrated effectiveness in ND-BC patients, leading to favourable pCR rates and enabling breast-conserving surgery. Predictive markers for pCR varied depending on histologic types, with HER2 expression, ER status, Ki-67, and histologic grade showing significance in non-ductal subtypes, while HER2 status alone was predictive in lobular carcinoma. KEY WORDS Neoadjuvant chemotherapy, Non-ductal breast cancer, Lobular carcinoma.

Abstract
Objective: To investigate the impact of relative locations of multiple foci and microsatellite status of sporadic, synchronous, multiple, primary, colorectal carcinomas on clinicopathological features and prognosis. Methods: The clinicopathologic and prognostic data of 278 patients with sporadic, synchronous, multiple, primary, colorectal carcinomas who had been admitted to the Department of Colorectal Surgery at Zhejiang Cancer Hospital from January 2008 to July 2022 were retrospectively collected. The patients were categorized into three groups based on the relative locations of their multiple cancer foci: (1) a right-sided group that comprised patients with multiple cancer foci in the cecum, ascending colon, hepatic flexure of the colon, and transverse colon; (2) a left-sided group that comprised patients with multiple cancer foci in the splenic flexure of the colon, descending colon, sigmoid colon, and rectum; and (3) a left- and right-sided group that comprised patients with multiple cancer foci in the right half of the colon and left half of the colon/rectum. Additionally, the patients were further divided into two groups based on microsatellite status: a high microsatellite instability (MSI-H) and a low MSI/stable MSI (MSI/L&MSS) group. We compared differences in clinical characteristics and prognostic indicators between these groups. The χ2 test was utilized to compare selected clinical characteristics, whereas Kaplan-Meier survival analyses and log-rank tests were performed to compare their effects on prognosis. Result: Among 278 patients with SSCRC, 256 (92.1%) presented with two cancer foci and 22 (7.9%) with more than two foci. Additionally, 255 patients (91.7%) had adenocarcinomas, whereas the remaining 23 (8.3%) had mucinous adenocarcinomas. Lymph node metastases were identified in 136 patients (48.9%); the cancer foci had infiltrated beyond the muscular layer in 238 (85.6%); and 147 patients (52.9%) were diagnosed with TNM Stage III-IV disease. There were 155 patients (55.8%) in the left-sided group, 55 (19.8%) in the right-sided group, and 68 (24.5%) in the left- and right-sided group. Immunohistochemical examination of all four mismatch repair proteins were performed in 199 cases, revealing that 166 of these patients had MSI/L&MSS and 33 MSI-H disease. In the left-sided, left- and right-sided, and right-sided groups, the proportion of women was 16.8% (26/155), 26.5% (18/68), and 49.1% (27/55), respectively; these differences are statistically significant (χ2=22.335, P<0.001). The proportions of patients with more than three cancer foci were 5.2% (8/155), 16.2% (11/68), and 5.5% (3/55), respectively; these differences are statistically significant (χ2=8.438, P=0.015). The proportions of mucinous adenocarcinomas were 4.5% (7/155), 8.8% (6/68), and 18.2% (10/55), respectively; these differences are statistically significant (χ2=10.026, P=0.007). The proportions of patients with lymph node metastases were 55.5% (86/155), 48.5% (33/68), and 30.9% (17/55); these differences are statistically significant (χ2=9.817, P=0.007). The proportions of patients with Stage T3 & T4 disease in each group according to location were 81.3% (126/155), 88.2% (60/68), and 94.5% (52/55), respectively; these differences are statistically significant (χ2=6.293,P=0.043). The proportions of TNM Stage III-IV tumors were 59.4% (92/155), 54.4% (37/68), and 32.7% (18/55), respectively; these differences are statistically significant (χ2=11.637, P=0.003). Age, size of cancer foci, presence of distant metastasis, adenoma, nerve invasion, and vascular invasion did not differ significantly between the three groups (all P>0.05). Compared with those with MSI-H, patients with MSI/L&MSS disease were more likely to be aged >65 years and male (50.6% [84/166] vs. 15.2% [5/33], χ2=13.994,P<0.001; 80.7% [134/166] vs. 54.5% [18/33], χ2=10.457,P=0.001), more likely to be in the left-sided group (63.3% [105/166] vs. 24.2% [8/33], χ2=18.232, P<0.001), had a higher proportion of cancer foci of diameter <4 cm (54.8% [91/166] vs. 33.3% [11/33], χ2=5.086,P=0.024), and a lower proportion of mucinous adenocarcinomas (4.2% [7/166] vs. 27.3% [9/33], χ2=19.791,P<0.001), more likely to develop distant metastases (22.3% [37/166] vs. 6.1% [2/33], χ2=4.601,P=0.032), more likely to have lymph node metastases (57.2% [95/166) vs. 24.2% [8/33], χ2=11.996,P<0.001) and nerve invasion (28.9% [48/166] vs. 6.1% [2/33], χ2=7.643, P=0.006), had a higher proportion of TNM Stage III-IV disease (60.2% [100/166] vs. 24.2% [8/33], χ2=14.374, P<0.001), and a smaller proportion of family history of tumors (28.9% [48/166] vs. 60.6% [20/33], χ2=12.228, P<0.001). All the above-listed differences are statistically significant (all P<0.05). The differences in number of cancer foci, depth of infiltration, presence or absence of adenomas, and vascular invasion were not statistically significant (all P>0.05). In the 33 patients with MSI-H status and mismatch repair protein loss, the highest frequency of deletion was found in PMS-2 (66.7%, 22/33), followed by MLH-1 (57.6%, 19/33), whereas the proportions of MSH-2 (33.3%, 11/33) and MSH-6 (24.2%, 8/33) deletions were relatively low. There were statistically significant differences in the 3-year overall survival rates among the groups according to relative locations of cancer foci. The 3-year overall survival rates were 96.8%, 79.6%, and 88.5% in the right-sided, left- and right-sided, and left-sided groups, respectively (P=0.021). As to microsatellite status, the 3-year overall survival rate of patients with MSI-H disease was 93.8%, which is significantly better than the 78.4% for those with MSI/L & MSS (P=0.026). Conclusions: Among sporadic, synchronous, multiple, primary, colorectal carcinomas, those with right-sided disease had the deepest local infiltration, whereas those with left-sided disease had the greatest number of lymph node metastases, most advanced clinical TNM stage, lowest percentage of MSI-H disease, and the poorest prognosis.

Abstract
BACKGROUND Appendiceal tumors are considered to be a relatively rare tumor of the gastrointestinal tract and the prognosis is unclear. This study comprehensively investigated trends in the epidemiology and survival of appendiceal tumors in the United States over the past approximately 20 years. METHODS Patients with pathologically confirmed appendiceal tumors from 2000 to 2017 were selected from the Surveillance, Epidemiology and End Results (SEER) database. Age-adjusted incidence rates were calculated by SEER*Stat 8.4.0. The Kaplan-Meier method was used to analyze survival and prognostic factors were investigated by a multivariate Cox proportional risk model. RESULTS Ultimately, 13,546 patients with appendiceal tumors between 2000 and 2017 were included. The annual incidence of colonic adenocarcinoma and mucinous adenocarcinoma remained relatively stable. Interestingly, the annual incidence of appendiceal neuroendocrine tumors (aNETs) increased significantly, from 0.03 to 0.90 per 100,000 person-years, with the most dramatic increase in the number of patients with localized disease. Patients with aNETs showed a significant improvement in survival between 2009-2017, compared to the period 2000-2008. Moreover, this improvement in survival over time was seen at all stages (localized, regional, distant) of aNETs. However, this improved survival over time was not seen in colonic and mucinous adenocarcinoma. CONCLUSIONS The incidence of appendiceal neoplasms has increased significantly over the past nearly two decades, which is mainly due to the increased incidence and significant migration to earlier stages in aNETs. We must note that despite the increased incidence of aNETs, survival rates have improved at different disease stages.

Abstract
BACKGROUND Mucinous gastric carcinoma (MGC) is a distinct histologic subtype of gastric cancer (GC) that is often diagnosed at an advanced stage. The clinicopathological characteristics and prognosis of MGC, when compared to adenocarcinoma and signet-ring cell carcinoma (SRCC), are currently subjects of debate and require further investigation. METHODS In this study, we conducted an investigation on 4,417 patients who were hospitalized with GC at Zhejiang Cancer Hospital between April 2008 and December 2019. The objective was to compare the prognosis and clinicopathological characteristics of MGC with other types of GC. RESULTS In comparison to adenocarcinoma, MGC patients exhibited more advanced tumor infiltration (p < 0.001), lower tumor differentiation (p < 0.001), and higher rates of preoperative tumor marker positivity (except for AFP and CA125) (all p < 0.05). However, after propensity score matching (PSM) to eliminate confounding factors, MGC patients surprisingly exhibited a better prognosis than adenocarcinoma patients (p = 0.008), and the results in multifactorial COX regression were similar (HR = 0.792, 95% CI 0.629-0.997, p = 0.047). Among patients with MGC, age, pN stage, as well as preoperative levels of CA125 and CA724 (all p < 0.05), emerged as independent prognostic markers. While overall survival did not significantly differ between MGC and SRCC (p = 0.196), significant survival disparities emerged in advanced-stage patients (p = 0.009), with MGC showing better survival rates. Furthermore, a nomogram was developed to predict 1-, 3-, and 5-year survival in gastric cancer patients based on various factors, achieving a C-index of 0.772 (95% CI: 0.745-0.799). CONCLUSIONS While the poorer prognosis associated with MGC may be linked to its advanced stage and lower degree of differentiation, its biological behavior could contribute to improved survival.

Abstract
Appendiceal adenocarcinomas (AA) are a rare and heterogeneous mix of tumors for which few preclinical models exist. The rarity of AA has made performing prospective clinical trials difficult, which has partly contributed to AA remaining an orphan disease with no chemotherapeutic agents approved by the FDA for its treatment. AA has a unique biology in which it frequently forms diffuse peritoneal metastases but almost never spreads via a hematogenous route and rarely spreads to lymphatics. Given the localization of AA to the peritoneal space, intraperitoneal delivery of chemotherapy could be an effective treatment strategy. Here, we tested the efficacy of paclitaxel given by intraperitoneal administration using three orthotopic patient-derived xenograft (PDX) models of AA established in immunodeficient NSG mice. Weekly intraperitoneal paclitaxel treatment dramatically reduced AA tumor growth in all three PDX models. Comparing the safety and efficacy of intravenous with intraperitoneal administration, intraperitoneal delivery of paclitaxel was more effective, with reduced systemic side effects in mice. Given the established safety record of intraperitoneal paclitaxel in gastric and ovarian cancers, and lack of effective chemotherapeutics for AA, these data showing the activity of intraperitoneal paclitaxel in orthotopic PDX models of mucinous AA support the evaluation of intraperitoneal paclitaxel in a prospective clinical trial. SIGNIFICANCE The activity and safety of intraperitoneal paclitaxel in orthotopic PDX models of mucinous appendiceal adenocarcinoma supports the evaluation of intraperitoneal paclitaxel in a prospective clinical trial of this rare tumor type.

Abstract
Background Monocytes and monocyte-derived tumor infiltrating cells have been implicated in the immunosuppression and immune evasion associated with pancreatic adenocarcinoma (PDAC). Yet, precisely how monocytes in the periphery and tumor microenvironment in patients with intraductal papillary mucinous neoplasm (IPMN), a precursor lesion to PDAC, change during disease progression has not been defined. Here we functionally profiled the peripheral immune system and characterized the tumor microenvironment of patients with both IPMN and PDAC. We also tested if sera from patients with IPMN and PDAC functionally reprogram monocytes relative to that of healthy donors. Methods Pancreatic tissue and peripheral blood were collected at the time of resection from 16 patients with IPMN and 32 patients with PDAC. Peripheral blood and pancreatic tissue/tumor were immunophenotyped using flow cytometry. Whole blood was plated and incubated with R848 (a TLR 7/8 agonist) or LPS (a TLR4 agonist) for 6 hours and TNF expression in monocytes was measured by flow cytometry to measure monocyte activation. To test if TLR sensitivity is determined by factors in patient sera, we preconditioned healthy donor monocytes in serum from PDAC (n=23), IPMN (n=15), or age-matched healthy donors (n=10) followed by in vitro stimulation with R848 or LPS and multiplex cytokine measurements in the supernatant. Results TNF expression in R848-stimulated peripheral blood monocytes was higher in patients with low grade vs high grade IPMN (65% vs 32%, p = 0.03) and stage 1 vs stage 2/3 PDAC (58% vs 42%, p = 0.03), this was not observed after LPS stimulation. TLR activation correlated with increasing grade of dysplasia from low grade IPMN to high grade IPMN. Serum from patients with IPMN and PDAC recapitulated suppression of TNF induction after R848 stimulation in naïve, healthy donor monocytes. Conclusion Peripheral blood monocyte TNF secretion inversely correlates with the degree of dysplasia in IPMN and cancer stage in PDAC, suggesting innate immune reprogramming as IPMNs progress to invasive disease. These effects are, at least in part, mediated by soluble mediators in sera.

Abstract
The prognostic significance of radiotherapy (RT) for colorectal cancer (CRC) has shown conflicting results, particularly among different pathological subtypes, including adenocarcinoma (AC), mucinous adenocarcinoma (MC), and signet-ring cell carcinoma (SR). This study analyzed the prognosis of three pathological CRC types and focused on the prognostic significance of RT on three CRC histological subtypes. Patients diagnosed with AC (n = 54,174), MC (n = 3813), and SR (n = 664) in the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database (2010-2017) were evaluated. Cox regression models and competitive risk models were built to assess the effect of RT on the risk of CRC-associated death. Potential interactions between RT and stratified variables including age, sex, and tumor location were examined by multiplicative models. Compared with AC patients, SR patients had the worst overall survival (OS) among 3 subtypes of CRC (log-rank test, p < 0.001). Compared with patients who did not receive radiotherapy, RT was associated with a 1.09-fold (HR = 1.09, 95%[CI]: 1.03, 1.15) elevated risk of death among AC patients. In the SR group, RT significantly reduced the risk of death by 39% (HR = 0.61, 95%[CI]: 0.39-0.95). However, RT did not appear to independently influence survival in the MC group (HR = 0.96, 95%[CI]: 0.77, 1.21). In the subgroup analysis, tumor location (colon and rectum) significantly modified the association between RT and the risk of death among the AC and SR patients (p for interaction < 0.05). SR patients exhibited a worse OS (overall survival) than AC patients, and the effect of RT varied according to CRC histological subtypes. This can ultimately lead to more personalized and effective treatment strategies for CRC patients.

Abstract
Similar to PAX8, SOX17 was recently identified as a master transcription factor of ovarian cancer based on RNA sequencing data. We explored SOX17 utility in diagnosing ovarian tumors and other gynecologic tumors. We systematically evaluated SOX17 expression on tissue microarrays of 398 ovarian tumors of various types, 93 endometrial carcinomas, 80 cervical carcinomas, and 1371 nongynecologic carcinomas, such as those of kidney, thyroid, breast, colon, bladder, liver, bile duct, adrenal gland, pancreas, brain, and lung and malignant melanoma. In addition, we evaluated SOX17 expression in whole tissue sections from 60 gynecologic carcinomas and 10 angiosarcomas. The results demonstrated that SOX17 was highly expressed in most ovarian and endometrial tumors with strong intensity. However, unlike PAX8, it was predominately negative in other tested tumor types, including kidney and thyroid tumors. In particular, SOX17 was highly expressed in the following pathologic subtypes of ovarian tumors: serous carcinoma, clear cell carcinoma, endometrioid carcinoma, and germ cell tumors. SOX17 was mostly negative in mucinous carcinoma and sex cord stromal tumors. In addition, SOX17 was expressed in vascular endothelial cells and was positive in all tested angiosarcomas. In summary, our results demonstrate that SOX17 is a sensitive and specific marker for ovarian nonmucinous carcinomas and endometrial carcinomas. For ovarian germ cell tumors and angiosarcomas, SOX17 demonstrates higher specificity than PAX8, with comparable sensitivity. Furthermore, SOX17 positivity in endothelial cells serves as an internal positive control, making it an excellent marker.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) represents the most common primary pancreatic malignancy. An understanding of the cytomorphologic features of conventional ductal adenocarcinoma and its variants is important to ensure accurate diagnoses. METHODS The clinicopathological and cytological data of serous fluids in PDAC patients were obtained from the electronic medical records and pathology database. All samples were analyzed and reclassified according to the "The International System for Reporting Serous Fluid Cytopathology" guidelines. Cytomorphologic features were examined with SurePath automatically prepared slides and stained using the Pap method in malignant (MAL) effusion specimens from 21 patients with PDAC. Immunocytochemical staining was conducted on 12 cell blocks from MAL PDAC effusion. RESULTS A total of 137 serous fluids specimens of PDACs were included, among which 61 (44.5%), 9 (6.6%), 13 (9.5%), 52 (38.0%), and 2 (1.5%) patients were classified into malignancy, suspicious for malignancy, atypia of undetermined significance, negative for malignancy and nondiagnostic groups, respectively. The key cytologic features for the conventional type of PDAC included cohesive clusters of ductal cells in glandular crowding and disorganized "drunken honeycomb" pattern or intercalated duct-like structure with anisonucleosis, cytoplasmic vacuoles, and concomitant "Indian-file" configuration. Undifferentiated carcinoma was comprised of enlarged, undifferentiated, pleomorphic MAL cells. Adenosquamous carcinoma could show glandular and/or squamous differentiation. Colloid carcinoma was composed of three-dimensional cancer cell clusters floating in thick mucin. CONCLUSION Crowding and disorganized "drunken honeycomb" pattern or intercalated duct-like structure with anisonucleosis, may represent an important clue for diagnosing PDAC in serous fluids. Immunocytochemical staining in combination with review of medical records and cytomorphological data can serve as useful adjuncts for distinguishing between PDAC and its variants.

Abstract
AIM Cystic ovarian masses in children may be physiological or neoplastic. It is mandatory that suspected neoplastic lesions are resected without tumour spillage. However, a large midline incision is cosmetically unappealing incision to young women. Here we describe our experience of using controlled drainage without spillage that allows a cosmetic pfannenstiel approach without compromising oncological principles. METHOD All girls treated with large ovarian cystic masses since 2008 in our centre were identified and data was collected prospectively. A small pfannenstiel incision was performed followed by peritoneal washings; tissue glue was used to stick an Opsite™ dressing to the cyst surface and fluid drained so there was no leakage back into the patient. Once aspirated the cyst was delivered and an ovarian preserving cystectomy was performed where possible. RESULTS Twenty-three girls (median age 14.5 years (8.1 to 16.5 years) were included. Pre-operative MRI scan showed a complex lesions with median volume of 1169 ml (range 252-7077 ml). At surgery 22/23 cysts were intact and removed without spillage. HISTOLOGY mature teratoma (11), serous cyst (3), mucinous cyst adenocarcinoma (2), mucinous cystadenoma (5), Sertoli-Leydig tumour, sclerosing stromal tumour. One girl with pre-operative rupture of a mucinous adenocarcinoma subsequently died. Ovarian sparing cystectomy was performed in 17/23 girls. All other patients are well without evidence of recurrence. CONCLUSION This is the largest series in children and adolescents using controlled drainage of cystic ovarian tumours. Though there were a range of diagnoses we have shown that these can be removed safely with a cosmetic pfannenstiel approach while following oncological principles.

Abstract
The salivary gland section in the 5th edition of the World Health Organization Classification of Head and Neck Tumours features a description and inclusion of several new entities, including sclerosing polycystic adenoma, keratocystoma, intercalated duct adenoma, and striated duct adenoma among the benign neoplasms; and microsecretory adenocarcinoma and sclerosing microcystic adenocarcinoma as the new malignant entities. The new entry also includes mucinous adenocarcinoma subdivided into papillary, colloid, signet ring, and mixed subtypes with recurrent AKT1 E17K mutations across patterns suggesting that mucin-producing salivary adenocarcinomas represent a histologically diverse single entity that may be related to salivary intraductal papillary mucinous neoplasm (IPMN). Importantly, the number of entities in the salivary chapter has been reduced by omitting tumors or lesions if they do not occur exclusively or predominantly in salivary glands, including hemangioma, lipoma, nodular fasciitis and hematolymphoid tumors. They are now discussed in detail elsewhere in the book. Cribriform adenocarcinoma of salivary gland origin (CASG) now represents a distinctive subtype of polymorphous adenocarcinoma (PAC). PAC is defined as a clinically, histologically and molecularly heterogeneous disease group. Whether CASG is a different diagnostic category or a variant of PAC is still controversial. Poorly differentiated carcinomas and oncocytic carcinomas are discussed in the category "Salivary carcinoma not otherwise specified (NOS) and emerging entities". New defining genomic alterations have been characterized in many salivary gland tumors. In particular, they include gene fusions, which have shown to be tightly tumor-type specific, and thus valuable for use in diagnostically challenging cases. The recurrent molecular alterations were included in the definition of mucoepidermoid carcinoma, adenoid cystic carcinoma, secretory carcinoma, polymorphous adenocarcinoma, hyalinizing clear cell carcinoma, mucinous adenocarcinoma, and microsecretory adenocarcinoma.

Abstract
A 53-year-old lady presented with post-menopausal bleeding (spotting) for two days and abdominal pain for three months. CT scan revealed bilateral adnexal mass and ascites; and CEA and CA19.9 was raised. Histopathology of the resected tissues revealed mucinous carcinoma of bilateral ovaries and colon with omental metastasis. Generally, pseudomyxoma peritonei arises from primary ovarian or appendiceal adenomas or adenocarcinomas. Keywords: Adenocarcinomas; ascites; metastases; mucinous carcinoma; pseudomyxoma peritonei.

Abstract
Adenocarcinoma constitutes around 0.5 to 2% of all neoplastic lesions of the urinary bladder, out of which, the mucinous variant is seen on rare occasions. Intestinal metaplasia resulting from nephrolithiasis, chronic inflammation and hydronephrosis could be the precursor lesion. Bladder exstrophy and remnants of the urachus are considered as other possible risk factors. The tumour prefers patients who are over 50 years. Hematuria, difficult voiding and suprapubic pain are the most common presenting symptoms. The tumour has a very bad prognosis and is poorly responsive to chemo and radiotherapy and hence surgery is the treatment of choice. Hence early diagnosis is of paramount importance. While managing adenocarcinoma of the bladder, it is important to rule out any possibility of a metastatic lesion that could have come from other organs where mucinous adenocarcinoma is more common.

Abstract
BACKGROUND Jejunal lymphatic malformations are congenital lesions that are seldom diagnosed in adults and rarely seen on imaging. CASE PRESENTATION A 61-year-old Caucasian woman was initially diagnosed and treated for mucinous ovarian carcinoma. After an exploratory laparotomy with left salpingo-oophorectomy, a computed tomography scan of the abdomen and pelvis demonstrated suspicious fluid-containing lesions involving a segment of jejunum and adjacent mesentery. Resection of the lesion during subsequent debulking surgery revealed that the lesion seen on imaging was a jejunal lymphatic malformation and not a cancerous implant. CONCLUSIONS Abdominal lymphatic malformations are difficult to diagnose solely on imaging but should remain on the differential in adult cancer patients with persistent cystic abdominal lesions despite chemotherapy and must be differentiated from metastatic implants.

Abstract
Lynch syndrome is the most prevalent form of familial colorectal cancer (CRC) and is caused by pathogenic germline mismatch repair (MMR) gene mutations. MLH1, MSH2 and MSH6 mutations have been well studied, but the rate and characteristics of PMS2 mutations are rare, especially in China. This study enrolled 1706 unselected patients with CRC who underwent colorectal resection from June 2016 to November 2018, the MMR status and clinicopathological features were analysed. A total of 11.8% of patients with CRC had defects in at least one MMR-related protein. Among them, 8.3% were identified with PMS2 defects, and 3.1% of patients had isolated PMS2 defects. Compared with MMR-proficient CRC, PMS2-defect CRC occurred more frequently in the right colon and less frequently in the rectum, had more poorly differentiated and mucinous carcinoma cases, and had fewer perineural invasions and a lower pN stage but a more advanced pT stage and a larger tumour size. In the cases with PMS2 defect, there were fewer tumours in the right colon, fewer poorly differentiated cases and smaller tumour sizes than in the cases with both MLH1 and PMS2 defects. In addition, in cases with isolated PMS2 defects, there were more tumours in the right colon and, more mucinous carcinoma cases than in cases with MMR-proficient CRCs, but had a similar cancer onset age. This study identified the rate, clinicopathological and age characteristics of PMS2 defects in CRCs in China and highlighted the importance of universal screening and germline detection of PMS2 in CRC.

Abstract
BACKGROUND Recurrent acute pancreatitis (RAP) may be a presenting feature of and an indication for resection of pancreatic cysts, including intra-ductal papillary mucinous neoplasm (IPMN). Few data are available regarding the prevalence of malignancy and post-operative RAP in this population.
AIM To study the role of resection to help prevent RAP and analyze if presentation as RAP would be a predictor for malignancy.
METHODS This retrospective study assessed 172 patients who underwent surgical resection of pancreatic cystic neoplasms at a university hospital between 2002 and 2016. The prevalence of preoperative high-risk cyst features, and of neoplasia was compared between patients with and without RAP. To identify the cause of pancreatitis, all the patients had a detailed history of alcohol, smoking, medications obtained, and had cross-sectional imaging (contrast-enhanced computed tomography/magnetic resonance imaging) and endoscopic ultrasound to look for gallstone etiology and other structural causes for pancreatitis. The incidence of RAP post-resection was the primary outcome.
RESULTS IPMN accounted for 101 cases (58.7%) {[branch duct (BD) 59 (34.3%), main duct (MD) 42] (24.4%)}. Twenty-nine (16.9%) presented with RAP (mean 2.2 episodes): 15 had BD-IPMN, 8 MD-IPMN, 5 mucinous cystic neoplasm and 1 serous cystic neoplasm. Malignancy was similar among those with vs without RAP for all patients [6/29 (20.7%) vs 24/143 (16.8%)] and IPMN patients [6/23 (26.1%) vs 23/78 (29.5%)], although tended to be higher with RAP in BD-IPMN, [5/15 (33.3%) vs 3/44 (6.8%), P = 0.04]. At mean follow-up of 7.2 years, 1 (3.4%) RAP patient had post-resection RAP. The mean episodes of acute pancreatitis before vs after surgery were 3.4 vs 0.02 (P < 0.0001).
CONCLUSION Malignancy was not increased in patients with pancreatic cystic neoplasms who have RAP compared to those without RAP. In addition, specific cyst charac-teristics were not clearly associated with RAP. The incidence of RAP was markedly decreased in almost all patients following cyst resection.

Abstract
BACKGROUND Discontinuation of branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) surveillance after 5 years of no change remains controversial. Long-term outcomes of BD-IPMN without significant changes in the first 5 years were evaluated. METHODS We performed a multi-center retrospective analysis of patients with BD-IPMN diagnosis from 2005 to 2011 (follow-up until 2017). Significant changes were defined as pancreatic cancer (PC), pancreatectomy, high-risk stigmata (HRS), worrisome features (WF) and worrisome EUS features (WEUS). RESULTS Of 982 patients who had no significant changes, 5 (0.5%), 7 (0.7%), 99 (10.1%), 4 (0.4%) patients developed PC, HRS, WF, WEUS, respectively, post-5 years. PC and HRS/WF/WEUS incidences at 12 years were 1.0% and 29.0%, respectively. Patients that developed HRS/WF/WEUS had larger cyst size in first 5 years compared to those that did not [16 (12-23) vs. 12 (9-17) mm, p = 0.0001], cyst size of >15 mm having higher cumulative incidence of HRS/WF/WEUS. PC mortality was 0.8%; all-cause mortality was 32%. Incidence of mortality due to PC was higher in HRS/WF/WEUS group, p < 0.0001. The mortality rate at 12 years for ACCI (age-adjusted Charlson Comorbidity Index) of ≤3, 4-6, and ≥7 were 3.5%, 19.9%, and 57.6% (p < 0.0001), respectively. CONCLUSIONS Incidence of PC in patients with BD-IPMN without significant changes in first 5 years of diagnosis remains low at 1.0%. Incidence of HRS/WF/WEUS was higher at 29.0%. PC-related mortality was higher in HRS/WF/WEUS group. These risks should be weighed against patients' overall mortality (utilizing scoring systems such as ACCI) when making surveillance decision of BD-IPMN beyond 5 years.

Abstract
A 48-year-old female visited former doctor with abdominal pain and bloating. She was suspected of having pancreatic tumor and referred to our hospital. Abdominal dynamic CT showed multilocular cystic tumor in the pancreatic tail, and chest CT showed multiple lung nodules. From these findings, the patient was diagnosed mucinous cystic carcinoma(MCC)with lung metastases. We performed distal pancreatectomy for the first and lung resection after pancreatectomy. After all, the pathological diagnosis was MCC and metastatic lung cancer from the MCC. The adjuvant chemotherapy was not performed. Eleven months after pancreatectomy and 6 months after lung resection, the patient is still alive without recurrence.

Abstract
A 66-year-old Japanese man was referred to our hospital with multiple giant liver cysts. The cysts had already been detected as multiple 3-cm cysts with small nodules at another hospital 12 years prior to this presentation. The cysts were diagnosed as an intraductal papillary neoplasms of the bile duct (IPNB) occupying the right lobe of the liver. Extended right lobectomy was performed. Based on the pathological findings, the tumor was diagnosed to be an oncocytic-type IPNB with minimal invasion. This experience suggests that the progression of IPNBs occur relatively slowly. The present case might provide important information for understanding the natural history of IPNBs.

Abstract
A 53-year-old woman was referred to our hospital because of upper abdominal pain and expansion of the pancreatic main duct. Enhanced computed tomography revealed expansion of the main pancreatic duct from the head to the tail; in addition, a 30 mm cystic tumor was observed in the pancreatic head and a 56 mm tumor was observed in the ventral side of the pancreatic body. Endoscopy revealed fistula formation in the duodenum of the Vater papilla on the oral side. The patient was diagnosed with an intraductal papillary mucinous carcinoma(IPMC). In addition, PET-CT revealed accumulation of FDG in the ventral side of the pancreatic body, and a disseminated nodule in the omental bursa was suspected. We administered 6 courses of gemcitabine plus nab-paclitaxel therapy, after which, the tumor in the ventral side of the pancreatic body disappeared. We then performed sub-stomach-preserving pancreatoduodenectomy. The results of abdominal cavity washing cytology were negative, and there were no disseminated nodules in the omental bursa. Therefore, we could perform R0 excision.

An elevated CA 19-9 is associated with invasive cancer and worse survival in IPMN. Pancreatology 2020; 20:729-735.

Abstract
BACKGROUND Current guidelines for IPMN include an elevated serum carbohydrate antigen (CA) 19-9 among the worrisome features. However, the correlation of CA 19-9 with histological malignant features and survival is unclear. Serum CEA is also currently used for preoperative management of IPMN, although its measurement is not evidence-based. Accordingly, we aimed to assess the role of these tumor markers as predictors of malignancy in IPMN. METHODS IPMN resected between 1998 and 2018 at Massachusetts General Hospital were analyzed. Clinical, pathological and survival data were collected and compared to preoperative levels of CA 19-9 and CEA. Receiver operating characteristic (ROC) and Cox regression analyses were performed considering cut-offs of 37 U/ml (CA 19-9) and 5 μg/l (CEA). RESULTS Analysis of 594 patients showed that preoperative CA 19-9 levels > 37 U/ml (n = 128) were associated with an increased likelihood of invasive carcinoma when compared to normal levels (45.3% vs. 18.0%, P < 0.001), while there was no difference with respect to high-grade dysplasia (32.9% vs 31.9%, P = 0.88). The proportion of concurrent pancreatic cancer was higher in patients with CA 19-9 > 37 U/ml (17.2% vs 4.9%, P < 0.001). An elevated CA 19-9 was also associated with worse overall and disease-free survival (HR = 1.943, P = 0.007 and HR = 2.484, P < 0.001 respectively). CEA levels did not correlate with malignancy. CONCLUSION In patients with IPMN, serum CA19-9 > 37 U/ml is associated with invasive IPMN and concurrent pancreatic cancer as well as worse survival, but not with high-grade dysplasia. Serum CEA appears to have minimal utility in the management of these patients.

Abstract
BACKGROUND Mucinous adenocarcinoma (MAC) rarely occurs in the salivary glands, especially in the labial gland. MACs arising from the salivary glands are characterized by an aggressive behavior due to high invasiveness and a high rate of regional lymph node metastasis. CASE PRESENTATION Here, we report a case of MAC arising from the lower lip, shown to have elevated serum carcinoembryonic antigen (CEA) levels by the medical checkup. The tumor showed aggressive behavior and serum CEA levels increased with repeated recurrence. CEA has been shown to have surprisingly diverse functions in cell adhesion, intracellular and intercellular signaling, and complex biological processes such as cancer progression, inflammation, angiogenesis, and metastasis. A MAC arising from the salivary glands may have a poor prognosis because CEA is highly expressed. CONCLUSIONS Generally, serum CEA levels have not been used as tumor markers for salivary gland malignancies; however, it may be useful for MAC arising from salivary glands. We recommend prospective research to determine whether serum CEA estimation is useful as a component of routine pre-treatment workup for MACs arising from the salivary glands.

Abstract
A 79-year-old male presented with right inguinal mass and right leg pain. Laparoscopic right hemicolectomy was performed for transverse colon cancer(type 1, muc, pSS, pN1a, pStage Ⅲa)3 years and 6 months ago. We resected the mass located in the spermatic cord and reconstructed it using the Direct Kugel Patch. Histopathological examination revealed mucinous carcinoma and was diagnosed as a metastatic lesion. Local recurrence was detected in the spermatic cord 1 year after resection, and radical inguinal orchiectomy was performed. Six months after the surgery performed for local recurrence, repeated recurrence was detected in the mesh used for reconstruction. Because this recurrence time was short, the patient opted for chemotherapy; however, this resulted in tumor growth, and surgery had to be scheduled. We performed extended resection of the abdominal wall and reconstruction using the fascia lata tensor muscle flap. Although intestinal obstruction, aspiration pneumonia, and skin flap necrosis were observed, the patient was discharged on the 85th postoperative day and remained alive without recurrence for 17 months. Mucinous carcinoma tends to cause local recurrence and requires adequate surgical margin resection. Extended excision should be considered in such cases of repeated local recurrence without distant metastases.

Abstract
An 82-year-old man with a diagnosis ofintraductal papillary mucinous carcinoma(IPMC)underwent pancreaticoduodenectomy followed by adjuvant chemotherapy with S-1. Six months after surgery, he had upper abdominal pain, and CT demonstrated a recurrent intraabdominal tumor located at the surgical incision scar. It was diagnosed as a solitary peritoneal recurrence, and palliative radiation therapy at a dose of 30 Gy was performed for the relief of abdominal pain after administration ofoxycodone. He was free ofpain without pharmacological therapy and received subsequent chemotherapy with nabpaclitaxel plus gemcitabine(GnP). He remains free ofpain and alive without progression ofthe disease 24 months after recurrence. Hypofractionated-accelerated radiotherapy is feasible and results in pain relief for local recurrence of IPMC.

Abstract
OBJECTIVE To study the clinicopathologic features of small cell carcinoma of ovary, hypercalcemic type (SCCOHT) and to evaluate the diagnostic significance of loss of SMARCA4 expression. METHODS The clinicopathologic characteristics of 5 cases of SCCOHT were reviewed. The expression of SMARCA4 protein was detected by immunohistochemistry in the cases of SCCOHT and 240 cases of other primary malignant tumors of ovary and peritoneum. RESULTS The mean and medium age of these patients was 30 years and 28 years, respectively. The presenting symptoms included abdominal pain, distention and a pelvic mass. Hypercalcemia was found in 3 patients. The maximum diameter of tumors ranged from 13.5 to 22.0 cm. Extraovarian spread was demonstrated in all of the patients on presentation. Histologically, the tumors were composed of closely packed small round cells with scanty cytoplasm, hyperchromatic nuclei and irregular chromatin clumps. The tumor cells grew in sheets, nests, cords or trabecular pattern. Follicle-like spaces were observed in 4 cases. Three of the tumors contained large cells with abundant eosinophilic cytoplasm. Spindle cell morphology was found in 1 case. There were 2 cases with myxoid or hyaline stroma. Four out of five of SCCOHT cases showed loss of SMARCA4 protein while only 6.3% (15/240) of the other primary malignant tumors of ovary and peritoneum , including undifferentiated carcinoma (1/5), high-grade serous carcinoma (4.6%, 5/109), endometrioid carcinoma (7.7%, 2/26), clear cell carcinoma (1/9), mucinous carcinoma (1/5), mixed carcinoma (4.9%, 3/61), carcinosarcoma (1/9) and high-grade serous carcinoma of peritoneum (1/9), were negative. CONCLUSIONS SCCOHT is a rare malignant tumor and often misdiagnosed as other types of ovarian small cell tumor. Loss expression of SMARCA4 protein is characteristic and facilitates the diagnosis and differential diagnosis of SCCOHT.

Abstract
OBJECTIVE To investigate the differences of clinical characteristics and molecular features among colorectal cancer subsides and provide evidence for colorectal cancer protection, diagnosis and treatment. METHODS All of 4 316 colorectal patients from Shanghai cancer center were selected for clinical character analysis, among which, 2 224 subjects for molecular feature analysis. Clinic pathological characteristics like age, gender, tumor types, histological types, differentiation and T-stage, as well as molecular features like hMLH1, hMSH2, CD44, p21, p53, COX2,E-cadherin, Her2 and Ki-67, were involved into this research. RESULTS It showed that compared with left-sided colon and rectal cancers, right-sided cancers occurred more in women (46.0% (541/1 176); 39.2% (424/1 083); 41.2% (848/2 057), respectively, χ² = 11.85, P < 0.01), had more mucinous or signet-ring carcinoma (12.0% (128/1 064), 5.8% (56/960), 4.0% (75/1 859), respectively, χ² = 31.27, P < 0.01), poor differentiated carcinoma (32.1% (343/1 069), 19.5% (201/1 033), 19.3% (380/1 967), respectively, χ² = 72.66, P < 0.01) , and advanced T stage (87.9% (992/1 129), 83.2% (869/1 045), 72.2% (1 486/2 057), respectively, χ² = 121.44, P < 0.01). Meanwhile, the rates of hMLH1 were higher in right-sided colon cancers when compared with rectal cancers (13.4% (59/439) vs 8.5% (88/1 035), OR (95%CI): 1.67 (1.18-2.37)), as well as the rates of hMSH2 negative expression (4.9% (22/452) vs 2.4% (26/1 083), OR (95% CI): 2.08(1.17-3.71)). The rates of p53 positive expression were higher in right-sided colon cancers when compared with rectal cancers (76.2% (321/421) vs 68.4%, (776/1 134), OR (95% CI): 0.68 (0.52-0.87)). Compared with right-sided colon cancers, the rates of Her2 positive expression were higher in rectal cancers (19.3% (176/913) vs 13.2% (45/340), OR (95% CI): 1.57 (1.10-2.23)) , as well as the rates of Ki-67 expression which was positive in more than 50% cells (73.6% (840/1 141) vs 65.6% (299/456), OR (95% CI): 0.68 (0.54-0.86)). CONCLUSION There are specific characteristics in right-sided colon cancers. The difference of molecular features between right-sided colon and rectal cancers are more significant.

Abstract
OBJECTIVE To explore the clinicopathological features, treatment and prognosis of renal mucinous tubular and spindle cell carcinoma (MTSCC). METHODS The clinicopathological data of eleven patients of pathologically confirmed renal MTSCC were reviewed retrospectively. Among the 11 patients, there were 4 males and 7 females with a mean age of 51.6 years (range, 24 to 81 years). Two patients presented with hematuria, one presented with lumbago and others were asymptomatic. RESULTS The renal MTSCC was of hypovascular tumor in enhanced CT scan. Seven cases were treated with radical nephrectomy, and the other four with partial nephrectomy. The mean diameter of tumors was 4.4 cm. The TNM stages were as follows: pT1aN0M0 in 6, pT1bN0M0 in 3, pT2N0M0 in 2 cases. Histological examination of the tumors showed that they consisted of spindle cells arranged in tubular and trabecular patterns embedded in a myxoid stroma. No recurrence or metastasis was observed during the follow-up (median 41 months). CONCLUSIONS MTSCC is a rare low-grade renal epithelial carcinoma with a relatively good prognosis. Preoperative CT scan is partly helpful for diagnosis and guiding decision making. Nephron-sparing surgery is recommended in most cases, especially in patients with small tumors.

Abstract
Studies concerning adjuvant systemic therapy and prognosis in male breast carcinoma (MBC) are limited. We aimed to evaluate outcome of the changing practices of adjuvant systemic treatment and survival in operable MBC patients over the last two decades. The medical records of 148 MBC patients followed between the years 1986 and 2009 at 7 cancer center were evaluated retrospectively. One hundred and eighteen operable non-metastatic patients had sufficient data were included the study. One hundred and eighteen operable MBC were found to be eligible. Median age was 60 (range 29-83) years. Thirty-two percent of the patients had T3-4 tumors. Half of the patients had axillary lymph node-positive disease. The proportion of positivity of estrogen receptor(ER), progesterone receptor (PgR), and HER2 status were 82.9, 75.8, and 23.4%, respectively. Only, 7 patients had triple negative (TN). Adjuvant hormonotherapy was advised for 76.8% whereas adjuvant chemotherapy for 73.7% of the patients. Median follow-up was 40.9 months (range 3.8-186 months). Locoregional and/or distant recurrence developed in thirty-eight patients (32.2%). Twenty-three patients died during the follow-up period. Five-year disease-free survival (DFS) was found to be 60%, whereas overall survival (OS) was 82%. Larger tumor size and lymph node positivity were statistically significant poor prognostic factors for OS. Although statistical insignificant, patients with HER2-positive tumors have worse DFS (52 vs. 120 months, log rank P = .73) and OS (85 vs. 144 months, log rank P = .30) than HER2-negative ones. Although the frequency of the use of adjuvant systemic therapy in MBC has been increasing and survival rates improving for the last decades, lymph node status and tumor size are still the most important determining factors for prognosis. There is a need for further prognostic information in men with HER2-positive or TN breast cancer.

Abstract
BACKGROUND Among biomarkers, cancer-antigen 125 (CA-125) is the most studied. We propose an analytical tool to track ovarian carcinoma biomarkers, that is, the MALDI mass spectrometry imaging. MATERIAL/METHODS Ovarian carcinomas and benign ovaries were directly analyzed by MALDI-TOF-MS. After automatic profiling and mass spectrometry imaging analyses, hierarchical clustering based on principal component analysis in nonsupervised mode was carried out. On the same samples, preparations were performed to investigate peptides, then proteins, followed by high mass proteins, in an automatic profiling to specific signatures for diagnosis. Using tissue bottom-up strategy on tissue digestion, and mass spectrometry imaging after by shotgun sequencing by nalano-LC-IT-MS in MS/MS mode from washing samples from on tissue digested peptides, several biomarkers were found. RESULTS A list of specific biomarkers from the ovarian carcinoma regions was obtained and classified as proteins associated with cell proliferation, involved in immune response modulation, signaling to the cytoskeleton, and tumor progression. These specific biomarkers were then validated by immunocytochemistry using Tag-mass technology, cell biology, Western blot, and by PCR (using SKOV-3 ovarian epithelial cancer cells). A link between the immune regulation (innate immunity, tolerance) and virus cause is also discussed. CONCLUSIONS From the biomarkers identified, proteins involved in immune response modulation and cell proliferation have been pointed out in this study. Two new markers have been identified using such a strategy, that is, fragment C-terminal of the PSME1 (Reg-Alpha) and mucin-9.
