BACKGROUND: Krukenberg tumors are among rare cases of metastatic ovary cancers. They are presented as a solid mass which generally has bilateral and sometimes cystic components and is also known through symptoms related to the mass effect and/or hormonal imbalance. However, they may present findings before the primary tumor or remain asymptomatic for a long time. CASE REPORT: We presented a patient, who was diagnosed with gallbladder cancer nine years ago and whose adjuvant treatment was completed, applied to the outpatient clinic with the complaint of vaginal bleeding. Surgery was recommended to the patient and the patient was diagnosed with metastatic signet ring cell gallbladder cancer. The patient was started on gemcitabine-capecitabine treatment after surgery. CONCLUSION: The case is important both due to the rareness of metastasis of gall bladder cancer on the ovaries and also the detection of metastasis following the nine-year recurrence-free period. This case shows that routine controls including a careful gynecological examination in a patient primarily detected to have gastrointestinal malignity are important for recognizing late metastases.

PURPOSE: This study aimed to analyze the clinicopathological features and treatment outcomes of ovarian metastasis from gastric cancer. METHODS: This study included 155 female patients with unresectable advanced or recurrent gastric cancer at the Kochi Medical School between January 2007 and December 2021. A review of patients with ovarian metastasis was conducted, and their clinicopathological information and survival outcomes were compared with respect to ovarian metastasis. RESULTS: Fifteen patients were diagnosed with ovarian metastasis from gastric cancer with a median age of 54 years (range: 30-87 years) and an incidence of 9.7%. The median age of patients who developed ovarian metastasis was significantly lower those without ovarian metastasis (54 years vs. 71 years, P = 0.014). The median survival time (MST) for 15 patients with unresectable advanced gastric cancer who developed ovarian metastasis was 21.4 months (range: 0.2-41.4 months). The MST for 15 patients who underwent surgical resection and systemic drug treatment including chemotherapy to ovarian metastasis was significantly higher than those who received systemic drug treatment alone (28.1 months vs. 10.0 months; P = 0.021). CONCLUSION: Ovarian metastasis was found in 9.7% of female patients with unresectable advanced or recurrent gastric cancer and in younger patients than in those without ovarian metastasis. Multidisciplinary treatment, including surgical resection and systemic drug treatment for ovarian metastasis from gastric cancer, may benefit selected patients.

Krukenberg's tumor diagnosed in pregnancy is an uncommon situation that raises both diagnosis and medical management issues. We performed a review of the existing literature regarding this pathology, diagnostic means and therapeutic approaches, motivated by a case in our own practice. A 35-year-old primigravida was diagnosed with an adnexal mass during the first trimester prenatal ultrasound. Ultrasound revealed a 10 cm right adnexal mass with multiple septae, richly vascularized, whose presence and characteristics were confirmed by magnetic resonance imaging. Due to the progressively increasing tumor size, laparoscopy was performed with right adnexectomy and peritoneal biopsies. Histopathology diagnosed a metastatic ovarian tumor from a mucinous colorectal adenocarcinoma. After delivery the patient was further investigated and diagnosed with sigmoid cancer. Even though ovarian cancer in pregnancy is rare, adnexal ultrasound is mandatory when scanning during the first trimester to rule out the presence of associated fallopian or ovarian masses.

A 50s woman with a stomachache was referred to our hospital with diagnosed gastric cancer. Upper endoscopy showed a type 3 tumor in the lower gastric body, and CT demonstrated a pelvic tumor 10 cm in size. Laparoscopic surgery was performed; since the pelvic tumor was found to derive from the left ovary, left oophorectomy and total gastrectomy were performed. Pathological examination revealed that the ovarian tumor was a gastric cancer metastasis. Adjuvant chemotherapy with S-1 monotherapy was introduced. Four months after the operation, metastasis was suspected due to right ovary tumor edema. Due to the possibility of obtaining R0 resection and adverse events of chemotherapy, we chose right oophorectomy. Pathological examination demonstrated signet-ring cell cancer. Fourteen months after the first operation, the patient is alive with no recurrence or metastasis.

Generation of large amounts of genomic data is now feasible and cost-effective with improvements in next generation sequencing (NGS) technology. Ribonucleic acid sequencing (RNA-Seq) is becoming the preferred method for comprehensively characterising global transcriptome activity. Unique to cytoreductive surgery (CRS), multiple spatially discrete tumour specimens could be systematically harvested for genomic analysis. To facilitate such downstream analyses, laser capture microdissection (LCM) could be utilized to obtain pure cell populations. The aim of this protocol study was to develop a methodology to obtain high-quality expression data from matched primary tumours and metastases by utilizing LCM to isolate pure cellular populations. We demonstrate an optimized LCM protocol which reproducibly delivered intact RNA used for RNA sequencing and quantitative polymerase chain reaction (qPCR). After pathologic annotation of normal epithelial, tumour and stromal components, LCM coupled with cDNA library generation provided for successful RNA sequencing. To illustrate our framework's potential to identify targets that would otherwise be missed with conventional bulk tumour sequencing, we performed qPCR and immunohistochemical technical validation to show that the genes identified were truly expressed only in certain sub-components. This study suggests that the combination of matched tissue specimens with tissue microdissection and NGS provides a viable platform to unmask hidden biomarkers and provides insight into tumour biology at a higher resolution.

Ovarian metastasis from gastric cancer (Krukenberg tumor [KT]) has no consensus treatment and the role of surgical treatment is still controversial. Identifying prognostic factors for KT could help guide the management of this tumor. We used a meta-analysis to evaluate the prognostic value of metastasectomy and other factors in patients with KT to develop a treatment plan. We searched literature in PubMed, Cochrane library and EMBASE. We analyzed hazard ratios (HR) and 95% confidence intervals (CI) with respect to overall survival (OS). The meta-analysis included 12 cohort studies with 1,031 patients associated with longer OS following metastasectomy (HR = 0.41; 95% CI = 0.32-0.53; P < 0.001), R0 resection (HR = 0.37; 95% CI = 0.26-0.53; P < 0.001), metachronous ovarian metastasis (HR = 0.74; 95% CI = 0.58-0.93; P = 0.012), size of KT (<5 cm) (HR = 0.74; 95% CI = 0.58-0.95; P = 0.019), ECOG PS (Eastern Cooperative Oncology Group performance status) 0 to 1 (HR = 0.48; 95% CI = 0.29-0.80; P = 0.004), tumor confined to ovary (HR = 0.40; 95% CI = 0.16-0.99; P = 0.047), and tumor confined to pelvic cavity (HR = 0.36; 95% CI = 0.14-0.92; P = 0.033). Shorter OS was associated with peritoneal carcinomatosis (HR = 2.00; 95% CI = 1.25-3.21; P = 0.004), ascites (HR = 1.66; 95% CI = 1.19-2.31; P = 0.003) and positive CEA (HR = 1.41; 95% CI = 1.10-1.82; P = 0.007). Gastrectomy led to a slight improvement in OS, but without statistical significance (HR = 0.69; 95% CI = 0.47-1.02; P = 0.061). No significant difference in OS was observed in patients with signet-ring cells (HR = 1.17; 95% CI = 0.91-1.51; P = 0.226), bilateral ovarian metastasis (HR = 0.87; 95% CI = 0.70-1.08; P = 0.212), age ≥ 50 years (HR = 0.93; 95% CI = 0.71-1.22; P = 0.619), positive CA19-9 (HR = 1.01; 95% CI = 0.75-1.35; P = 0.960), and positive CA-125 (HR = 0.98; 95% CI = 0.73-1.33; P = 0.915). Various factors affect OS in patients with KT.

BACKGROUND: The treatment of metachronous Krukenberg tumor (mKT) from gastric cancer remains unexplored. We performed a literature review to evaluate whether or not surgical treatment improves survival. METHODS: A systematic review according to PRISMA guidelines was performed. Studies reporting on patients who underwent surgical treatment for mKT from gastric cancer were selected. Metachronous disease was divided as follows: confined to the ovaries, confined to the pelvis, or beyond the pelvis. Outcomes evaluated included overall survival (OS), progression-free survival (PFS), resection rate (R0), and factors predicting survival. RESULTS: 13 retrospective reports fulfilled the selection criteria (512 patients). Most of the patients presented at a premenopausal age. The median presentation interval from gastrectomy ranged from 16 to 21.4 months. Median OS ranged between 9 and 36 months. 1-year OS ranged between 52.5 and 59%, and 3-years OS between 9.8 and 36.5%. Resection margin, peritoneal seeding, and chemotherapy regimen and cycles influenced survival. CONCLUSION: Surgical treatment and adjuvant chemotherapy in patients with mKT from gastric cancer seems to be associated with improved survival and is justified especially in young patients. Disease location and R0 resection should be considered when selecting patients.

We report the first application of pressurized intraperitoneal aerosol chemotherapy (PIPAC) as a rescue therapy before palliative D2 gastrectomy combined with liver metastasectomy performed in a 49-year-old woman with peritoneal carcinomatosis who was primarily diagnosed with and underwent surgery for a Krukenberg tumor. The PIPAC procedure was performed with the use of cisplatin at 7.5 mg/m2 and doxorubicin at 1.5 mg/m2 for 30 min at 37 °C. Eight weeks after the PIPAC procedure, the patient underwent open classic D2 gastrectomy with the creation of a Roux-en-Y anastomosis (RNY) combined with liver metastasectomy. The patient underwent the classic protocol for chemotherapy combined with Xeloda. The patient felt better and returned to her daily activities. Multicenter data should be gathered to confirm the usefulness of PIPAC as a rescue or neoadjuvant supportive therapy in a very select group of patients who have been recently qualified to undergo classic chemotherapy or standard oncologic surgical procedures.

OBJECTIVE: A Krukenberg tumor is a malignancy in the ovary that metastasizes from a primary site. Here, we report a very rare case of bilateral Krukenberg tumors of the ovaries arising from a primary adenocarcinoma of the small intestine in a 53-year-old Taiwanese woman. CASE REPORT: The patient presented with a 3-month history of abdominal distension and acid regurgitation. Gastroscopy and colonoscopy findings were negative. According to the preoperative image, we highly suspected that the small bowel mass was the primary tumor with metastatic tumors to bilateral ovarian masses. The diagnosis was made immediately after operation. Results from pathology and immunohistochemical report confirmed our diagnosis. CONCLUSION: The primary lesion of a Krukenberg tumor is generally too small to be detected. Thus, careful radiographic and endoscopic exploration of the digestive system is necessary to detect the primary tumor. Immunohistochemical evaluation is also useful for determining the primary site of the adenocarcinoma.

La hemorragia obstétrica puede poner en riesgo la vida de la madre y del feto y a menudo se presenta de forma inesperada sin claros factores de riesgo. Su identificación precoz contribuye a no demorar las medidas de reanimación. Se presenta el caso de una rotura de metástasis ovárica durante el trabajo de parto responsable de sangrado masivo que obligó a una cesárea por pérdida de bienestar fetal, un inicio no descrito previamente en el tumor de Krukenberg. Los tumores malignos del embarazo son infrecuentes y difíciles de diagnosticar ya que sus manifestaciones clínicas a menudo se solapan con las del propio embarazo (dispepsia, náuseas y distensión abdominal). Un retraso en el diagnóstico comporta un pronóstico infausto a largo plazo. Se revisan las causas de sangrado obstétrico, subrayando la rareza del tumor de Krukenberg concomitante al embarazo (AU)
Obstetric haemorrhage can endanger the lives of mother and foetus. It often occurs unexpectedly without clear predictors. A high degree of suspicion helps to avoid delaying resuscitation measures. We present the case of a ruptured ovarian metastasis that occurred during labour. It caused a massive bleed forcing a caesarean section due to non-reassuring foetal status. This was an unprecedented and undescribed onset of Krukenberg tumour formation. Malignant tumours in pregnancy are rare and difficult to diagnose due to their clinical manifestations which often overlap with those of pregnancy itself (dyspepsia, nausea and bloating). Despite the available therapeutic measures, a delay in diagnosis is a determining factor for long-term prognosis. We review the causes of obstetric bleeding, and underline how rare Krukenberg tumours concomitant to pregnancy are (AU)

Metastatic ovarian tumours are extremely rare. The commonest primary site is usually stomach and the metastasis from this site is termed as krukenberg tumour. It accounts for 1-2% of malignant ovarian tumours. We present a case of 14 weeks' pregnancy with metastatic bilateral malignant ovarian tumour is presented. Diagnosis was made on ultrasound. Tumour markers were insignificant. Patient underwent staging laparotomy with total abdominal hysterectomy and bilateral salpingo oophorectomy and partial omentectomy. She also had haematemesis. Endoscopy revealed suspicious growth in stomach, but biopsy report excluded it. Case was handed over to the oncologist for further management.

A 34-year-old woman underwent total gastrectomy with D2 lymphadenectomy for gastric cancer, and the final diagnosis was T4N3M0, Stage III C, R0. Bilateral ovarian metastases were identified 51 months later, which were removed, and the patient received S-1 plus CDDP chemotherapy. Because the patient developed pubic bone metastasis 16 months after the second operation, we continued chemotherapy using paclitaxel with bisphosphonate. The patient was alive 70 months after the initial operation. The second patient was a 55-year-old woman who underwent total gastrectomy with D2 lymphadenectomy and was diagnosed with T2N2M0, Stage III A gastric cancer. Bilateral ovarian metastases were identified 72 months later, which were removed, and the patient received S-1 plus CDDP chemotherapy. The patient is alive with no signs of disease recurrence 96 months after the initial operation. For patients with ovarian metastases from gastric cancer, surgical resection in addition to chemotherapy might be an effective treatment. However, further studies and assessments of additional cases are needed to confirm the ideal treatment for this condition.

Krukenberg tumor with pregnancy is rare but it is a challenge for treatment and diagnosis. The authors report a case of a 29-week pregnant patient with a massive bilateral Krukenberg tumor which was misdiagnosed as myoma preoperatively and as ovarian stromal tumor intraoperatively. Prenatally the woman was asymptomatic except for preeclamptic symptoms, but red acne on the skin and elevated testosterone were observed. Pelvic ultrasound detected a heterogeneous solid mass mimicking a subserous myoma. The deterioration of preeclampsia prompted a cesarean section, but the neonate died nine days after he was born. A bilateral adnexal mass was found and considered as stromal tumor by frozen section because of luteinization of the stroma. The final pathology showed low differentiation adenocarcinoma of ovary, which was confirmed by gastric biopsies. The patient had undergone chemotherapy 16 times without surgical debulking and she was in generally well 1.5-year follow-up.

BACKGROUND: Mixed adenoneuroendocrine carcinoma is a rare tumor recently recognized as a new category in the last World Health Organization (WHO) classification of appendiceal tumors (2010). This term has been proposed to designate carcinomas of the appendix that arise by progression from a pre-existing goblet cell carcinoid. Mixed adenoneuroendocrine carcinomas are more aggressive tumors than typical goblet cell carcinoids and usually present with peritoneal spreading and ovarian masses. Staging, some histological features, and completeness of surgery are factors that determine its evolution. CASE PRESENTATION: We report the case of a mixed adenoneuroendocrine carcinoma--signet ring cell subtype--that presented as a Krukenberg tumor of unknown primary. CONCLUSION: The review of literature is focused on the most recent WHO pathologic classification of appendiceal tumors containing goblet cell clusters, which seems to correlate with prognosis. A management proposal for mixed adenoneuroendocrine carcinomas reported in previous literature is also discussed. This ranges from right hemicolectomy to cytoreduction plus hyperthermic intraperitoneal chemotherapy, in both cases usually followed by intravenous chemotherapy.

We evaluated the diagnostic value of hepatocyte nuclear factor 1 beta (HNF-1ß) and napsin A for diagnosing ovarian clear cell carcinoma. Immunohistochemical EnVision was used to measure HNF-1ß and napsin A expression in 38 cases of ovarian clear cell carcinoma, 30 cases of high-grade serous carcinoma, 22 cases of endometrioid adenocarcinoma, and 16 metastatic Krukenberg tumor cases. Then we found that HNF-1ß appeared in all ovarian clear cell carcinoma and was less common in high-grade serous and endometrioid adenocarcinoma (P < 0.05). However, no significant difference in HNF-1ß between clear cell carcinoma and metastatic Krukenberg tumor was found (P > 0.05). Napsin A was expressed in 97.4% of ovarian clear cell carcinoma, 6.7% high-grade serous carcinoma, 22.7% endometrioid adenocarcinoma, and 0% metastatic Krukenberg tumors. Napsin A in clear cell carcinoma was greater than that found in high-grade serous carcinoma, endometrioid adenocarcinoma, and metastatic Krukenberg tumor (P < 0.05). Sensitivity and specificity of HNF-1ß and napsin A for diagnosing ovarian clear cell carcinoma was 100% and 54.4%, and 97.4% and 89.7%, respectively. Sensitivity and specificity of HNF-1ß and napsin A for diagnosing ovarian clear cell carcinoma was 97.4% and 91.2%, respectively. So it is concluded that HNF-1ß and napsin A are more sensitive than currently used markers for diagnosing ovarian clear cell carcinoma. Moreover, napsin A is more specific than HNF-1ß. Combining HNF-1ß and napsin A may distinguish clear cell carcinoma from high-grade serous carcinoma, endometrioid adenocarcinoma and metastatic Krukenberg tumors.

The ovaries are common site of metastasis in a variety of primary neoplasms. Multiple tumors such as breast, lung, and pancreas have been reported to metastasize to the ovary, however; the colon and stomach are the most common primary cancer sites that of ovarian metastasis. An ovarian mass mostly originates from its self-tissue, but sometimes it can be a metastasis of a gastrointestinal system tumor. Such cases are often misdiagnosed as primary ovarian cancers. A 42-year-old woman was admitted to our hospital with pelvic pain. She had a history of her complaints for two months. Bilateral large ovarian mass was detected in transvaginal ultrasound. Laparotomy was performed, the pathologist suggested inspection of the stomach after the frozen section analysis; therefore, an irregular mass on the stomach was detected. The general surgeon was attended to the operation, and an inoperative stomach tumor was reported by the general surgeon. After that due to the partial obstruction of jejunum, a gastrojejunostomy was performed. It is in fact difficult to distinguish between metastatic mucinous carcinomas and primary mucinous carcinomas of the ovary, due to the similar appearance of as cystic tumors on gross examination. The clinicians should be aware of the likely concomitant gastrointestinal system tumor when a large and bilaterally mass was detected on physical examination. This case also reminds that a systemic examination is necessary even if the large ovarian tumors suspicious of primary malignancy were noticed.
