Tumores anexiales incidentales en cirugía abdominal / Incidental adnexal tumors in abdominal surgery

La posibilidad de encontrar una neoplasia benigna o maligna del ovario, de forma inesperada durante una intervención quirúrgica abdominal, es una realidad para todos los especialistas en cirugía. Si bien en muchos casos se tratará de una lesión benigna, el riesgo de cáncer no debe subestimarse, ya que, por ejemplo, la ruptura intraoperatoria de una lesión quística maligna puede reestadificar a una paciente con cáncer de ovario del estadio IA al IC, con todas las consecuencias que esto implica, como la necesidad de requerir quimioterapia adyuvante y tener un peor pronóstico. Por otro lado, en mujeres premenopáusicas debe discutirse con la familia o la paciente (idealmente) el riesgo e implicaciones de la ooforectomía uni o bilateral, incluso si esto amerita dejar el quirófano para obtener el consentimiento, o posponer el procedimiento definitivo para un segundo tiempo. La consulta intraoperatoria a un ginecólogo, siempre que sea posible, se debe llevar a cabo con el fin de respaldar la conducta adoptada. Conocer el manejo adecuado de las masas anexiales encontradas de forma incidental durante una cirugía abdominal, es una prioridad para todos los cirujanos generales.

The possibility of finding a benign or malignant neoplasm of the ovary unexpectedly during abdominal surgery is a reality for all specialists in surgery. Although in many cases it will be a benign lesion, the risk of cancer should not be underestimated, since, for example, the intraoperative rupture of a malignant cystic lesion may well re-stage a patient with ovarian cancer from stage IA to IC, with the consequences that this implies, such as the need for adjuvant chemotherapy and a worse prognosis. On the other hand, in premenopausal women, the risk and implications of unilateral or bilateral oophorectomy should be discussed with the family or the patient (ideally), even if this implies leaving the operating room to obtain consent, or postponing the definitive procedure for a second time. Intraoperative consultation with a gynecologist, whenever possible, should be carried out in order to support the adopted behavior. Knowing the proper management of adnexal masses found incidentally during abdominal surgery is a priority for all general surgeons.

A challenge for colorectal surgeons: pathogenesis, progression and management of the secondary tumors of the ovary / 中华胃肠外科杂志

A common clinical problem encountered by colorectal surgeons is the secondary tumors of the ovary (STO), particularly in young female patients. Most STO are from the digestive tract, and the known possible metastatic mechanisms include lymphatic, hematogenous, and intraperitoneal spreading. The molecular and histopathological characteristics of STO from different sites are diverse. It is particularly important to correctly identify the origin and feature of STO, which should be clarified by combining medical history, histopathology, immunohistochemistry, molecular biology, imaging and other means. The prognosis of patients with STO is poor in general. Comprehensive therapies based on surgical resection can benefit some patients. There is no specific treatment for STO at present, but not giving up easily on these patients is the right choice that every surgeon should understand.

Analysis of prognosis factors and follow-up strategy of ovary metastasis derived from gastric and colorectal cancer / 国际外科学杂志

Objective:To analyze the prognostic factors of Krukenberg tumors derived from the gastric cancer and colorectal cancer, so as to guide comprehensive treatment; looking for objective and sensitive indicators of ovarian metastasis during the follow-up after the surgery for gastric and colorectal cancer, which provides a basis for early diagnosis.Methods:Retrospectively analyzed the clinical data of 75 patients diagnosed with Krukenberg tumor admitted to Beijing Friendship Hospital, Capital Medical University from June 2007 to February 2020. Log-rank method and COX regression analysis were used to find independent prognostic factors. Wilcoxon rank sum test was used to compare the dynamic changes of ovarian imaging and tumor markers and to find the more sensitive indicators in the follow-up of patients with metachronous metastasis.Results:In the 75 cases, the univariate analysis suggested that CA19-9≥123.5 U/mL ( P=0.001), CA12-5≥37.9 U/mL ( P=0.018), Krukenberg tumor of stomach origin ( P=0.037), extra-ovary metastasis ( P=0.014), and without cytoreductive surgery (CRS) ( P<0.001)were poor prognostic factors. Among them, cytoreductive surgery could significantly improve the prognosis, even if with visible residual lesions, the overall survival was still significantly longer than those who have not undergone cytoreductive surgery ( P=0.004). Multivariate analysis results showed that CA19-9 and cytoreductive surgery ( P=0.001) were independent prognostic factors for patients with Krukenberg tumor; during the postoperative follow-up, ultrasound and CT imaging changes were more sensitive to ovarian metastasis ( P=0.006). Conclusions:CRS can prolong significantly the overall survival (OS) of patients with krukenberg tumor. Patients with simultaneous metastases should not give up the opportunity for surgery, and patients with metachronous metastases should also receive ovary resection procedure, even if with visible residual lesions, the patients can still benefit from the procedure. In the follow-up for gastric and colorectal cancer, attention should be paid to the ovarian ultrasound and CT imaging changes to facilitate early detection of ovarian metastases.

A rare case of steroid cell tumor of ovary: case report

Steroid cell tumors of the ovary account for less than 0.1% of all ovarian tumors. These tumors may present at any age with presentations related to the hormonal activity and virilizing properties of tumor. A 61-year-old postmenopausal women presented with complaints of postmenopausal bleeding for 15 days. Parity score of P3L3, not tubectomised. Menopaused 16 years back. History of weight loss noted. She is a known case of diabetes mellitus for 6 years not on any treatment and a known case of depressive disorder for 35 years on treatment on trihexphenidyl lurasidone. Had undergone sigmoid colon polyp removal in June 2018. On examination, P/A- mild gaseous distension (+). P/S- cervix flushed with vagina, pulled up cervix. P/V- uterus size and position couldn’t be made out, anterior fornix fullness (+). Ultrasonography showed bulky uterus with fibroid 4x4cm, endometrial thickness- 9 mm? Krukenberg tumor and posterior mediastinal lymph nodes. Patient underwent Total abdominal hysterectomy with bilateral salpingo-oophorectomy with frozen section on 01/07/19. Frozen section: 1. Ovaries: right ovary - fibrothecoma, left ovary- simple cyst. 2. Uterus- endometrial hyperplasia with atypia. 3. Myometrium- leiomyoma and adenomyosis. Postoperative period was uneventful. On microscopic examination, impression: right ovary- steroid cell tumor, uterus-endometrial hyperplasia with cytological atypia. Ovarian steroid cell tumors are grouped under sex chord stromal tumors and are usually benign, unilateral and characterized by a steroid cell proliferation. Steroid cell tumors are associated with androgenic changes with variable frequency, ranging from 12% to over 50% respectively. The primary treatment is surgical extirpation of the primary lesion and there are no reports of effective radiation or chemotherapy. In a young patient with stage IA disease, a unilateral salpingo oophorectomy is adequate.

Diagnosis and treatment strategy of gastric cancer with ovarian metastasis / 中华肿瘤杂志

Ovary is one of the common metastatic sites of gastric cancer. In the female patients, ovarian relapse is one of the most important causes of treatment failure for gastric cancer. The most likely mechanism of Krukenberg tumor development is via retrograde lymphatic spreading from gastric cancer. However, neither optimal treatment strategy nor standard treatment guideline for Krukenberg tumor from gastric cancer has been clearly established.The diagnostic key points consist of the previous or concomitant history of gastric cancer and the detection of ovarian solid tumors.The therapeutic regimens mainly include the metastasectomy, chemotherapy, radiotherapy and comprehensive treatment. Surgical resection of metastatic tumor combined with adjuvant chemotherapy can improve the prognosis and survival.

Peritonectomía con quimioterapia intraperitoneal hipertérmica en el tratamiento del tumor de Krukenberg. A propósito de un caso clínico / Peritonectomy with hyperthermic intraperitoneal chemotherapy in the treatment of Krukenberg tumor. A clinical case

Resumen ANTECEDENTES: el tumor de Krukenberg es una neoplasia caracterizada por metástasis ováricas de origen digestivo. El diagnóstico se establece en estadios avanzados de la enfermedad, mediante pruebas de imagen y determinación de marcadores inmunorreactivos relacionados con enfermedades del aparato digestivo. En la mayoría de los casos existe afectación bilateral en ambos anejos. OBJETIVO: reportar el caso de una paciente con tumor de Krukenberg. CASO CLÍNICO: paciente de 41 años de edad, intervenida de cáncer de mama hacía 10 años como único antecedente ginecológico de interés. Se diagnosticó con metástasis ovárica de adenocarcinoma gástrico primario, tratada con cirugía radical y quimioterapia hipertérmica intraperitoneal, con supervivencia de casi dos años entre el diagnóstico del tumor y su fallecimiento. CONCLUSIÓN: el tratamiento de estas neoplasias es muy agresivo, incluye cirugías radicales (peritonectomía) asociadas con quimioterapia para la carcinomatosis concomitante y técnicas hipertérmicas intraperitoneales. La supervivencia varía en función de las series reportadas y, en términos generales, se considera una neoplasia de muy mal pronóstico

Abstract BACKGROUND: These tumors are defined as metastatic ovarian adenocarcinomas of usually digestive origin. The few symptoms usually occurs when the disease is in advanced stages and, in most cases, with bilateral extension to both annexes. Krukenberg tumors frequently appear in young patients. Diagnosis is based on imaging tests and on the sensitivity of these tumors to specific immunoreactive markers, especially to those related to diseases of the digestive tract. OBJECTIVE: report the case of a patient with Krukenberg tumor. CLINICAL CASE: present the case of a patient who underwent breast cancer surgery 10 years ago as the only gynecological history of interest, who was diagnosed with ovarian metastases of primary gastric adenocarcinoma, treated with radical surgery plus intraperitoneal hyperthermic chemotherapy, and with survival of almost two years between tumor diagnosis and patient exitus. CONCLUSION: These therapies include radical surgeries such as peritonectomy, chemotherapy treatments aimed at treating associated carcinomatosis, and hyperthermic intraperitoneal techniques. Survival can vary depending on the series, and it is generally considered a disease of very poor prognosis.

Tumor de Krukenberg del ovario asociado a teratoma maduro / Krukenberg tumor of the ovary associated with mature teratoma

Se reporta un caso excepcional de tumor de Krukenberg ovárico bilateral asociado a teratoma maduro encontrado en una mujer de 54 años. La ecografía mostró al lado derecho tumor ovárico sólido de 55 mm y al lado izquierdo tumor quístico de 125 mm. Se realizó histerectomía total, salpingooforectomía bilateral, resección del epiplón mayor y muestras peritoneales. Al tercer día postcirugía, la paciente presentó signos de tromboembolismo pulmonar masivo y aunque recibió terapia anticoagulante falleció al quinto día postoperatorio. El estudio histológico mostró infiltración masiva de carcinoma de células en anillo positivas para citoqueratina en ambos ovarios. El ovario derecho mostró la forma sólida clásica del tumor de Krukenberg mientras que el ovario izquierdo correspondió a un quiste dermoide con infiltración tumoral de carcinoma de células en anillo en la pared.

An exceptional case of bilateral Krukenberg tumor of the ovary associated with mature teratoma presented in a 54 years old patient is reported. The ultrasound showed a 55 mm solid right ovarian tumor and a 125 mm left cystic ovarian tumor. Hysterectomy and bilateral salpingoophorectomy was performed including omental resection and peritoneal biopsies. Massive pulmonary embolism was detected in the third day after the surgery. Even anticoagulant therapy was established the patient died in the fifth postoperative day. The histological study revealed massive infiltration of signet ring cell carcinoma with positive expression for cytokeratin in both ovaries. The right ovary showed the classical solid form of the tumor. The left ovary was a dermoid cyst with signet ring cell carcinoma infiltrating the cystic wall.

Krukenberg tumors of gastric origin versus colorectal origin

OBJECTIVE: The aim of this study is to compare the each clinical manifestation related with its mean survival time of Krukenberg tumors (KTs) of gastric origin versus with that of colorectal origin. METHODS: A total of 156 consecutive patients diagnosed with KTs of the ovary who underwent surgical treatment at a single institution between 2001 and 2010 were retrospectively evaluated. Each clinical manifestation related with its mean survival time compared two different groups. Survival analyses and comparisons were performed using the Kaplan-Meier method. RESULTS: Among the 156 patients with KT, 111 patients with KTs of gastric origin and 45 patients with KTs of colorectal origin were identified. For all patients with KTs, median survival time was 22.7 months. Each mean survival time among all patients with KTs of gastric origin and colorectal origin was 19.2 months and 27.3 months. The results showed that mean survival time of postmenopausal patients was 19.0 months compared with 32.5 months for premenopausal patients (P=0.015). Among all patients, mean survival time of those with metachronous cancer was longer than those with synchronous cancer (P=0.001). In all cases, especially when only one ovary was invaded, the mean survival time was relatively higher (P=0.001). CONCLUSION: Patients with KTs of colorectal origin had a better prognosis than those of gastric origin. In all cases of KT, the mean survival time was significantly longer in postmenoposal patients, metachronous disease and unilateral ovarian involvement. Notably, synchronous, ascites positive, and ovary only metastasis showed more longer mean survival time in the KTs of colorectal origin than KTs of gastric origin.

Comparison of Surgery Plus Chemotherapy and Palliative Chemotherapy Alone for Advanced Gastric Cancer with Krukenberg Tumor / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: This study was conducted to validate the survival benefit of metastasectomy plus chemotherapy over chemotherapy alone for treatment of Krukenberg tumors from gastric cancer and to identify prognostic factors for survival. MATERIALS AND METHODS: Clinical data from 216 patients with Krukenberg tumors from gastric cancer were collected. Patients were divided into two arms according to treatment modality: arm A, metastasectomy plus chemotherapy and arm B, chemotherapy alone. RESULTS: Overall survival (OS) was significantly increased in arm A relative to arm B for patients initially diagnosed with stage IV gastric cancer (18.0 months vs. 8.0 months; p < 0.001) and those with recurrent Krukenberg tumors (19.0 months vs. 9.0 months; p=0.002), respectively. Metastasectomy (hazard ratio [HR], 0.458; 95% confidence interval [CI], 0.287 to 0.732; p=0.001), signet-ring cell pathology (HR, 1.583; 95% CI, 1.057 to 2.371; p=0.026), and peritoneal carcinomatosis (HR, 3.081; 95% CI, 1.610 to 5.895; p=0.001) were significant prognostic factors for survival. CONCLUSION: Metastasectomy plus chemotherapy offers superior OS when compared to palliative chemotherapy alone in gastric cancer with Krukenberg tumor. Prolonged survival applies to all patients, regardless of gastric cancer stage. Metastasectomy, signet-ring cell pathology, and peritoneal carcinomatosis were prognostic factors for survival. Future prospective randomized trials are needed to confirm the optimal treatment strategy for Krukenberg tumors from gastric cancer.

Tumor de Krukenberg / Krukenberg tumor

Introducción: el Krukenberg es un tumor metastático y representa del 1 por ciento al 2 por ciento de los tumores de ovario. El estómago es en el 70 por ciento de los casos la localización primaria más frecuente, seguidos por colon, apéndice y mama. El pronóstico es desfavorable y la evolución es rápida. Objetivo: describir un caso clínico de una paciente con tumor de Krukenberg. Presentación del caso: mujer de 53 años que consulta por sangramiento posmenopáusico a tipo manchas y dolor bajo vientre. Antecedentes personales de carcinoma gástrico, litiasis vesicular, nódulo de mama e hipertensión arterial. Se realizó estudio sonográfico ginecológico con marcadores para tumor de ovario positivos. Marcadores tumorales negativos. Resultados: hallazgo transoperatorio: se observó útero miomatoso y ambos ovarios multiloculados, superficie de revestimiento lisa de contenido mucinoso, con áreas sólidas de coloración heterogénea y consistencia renitente. Se realizó histerectomía con doble anexectomía. Conclusiones: el Krukenberg, tumor metastásico de ovario, es una entidad rara con mal pronóstico luego de su diagnóstico. Aún así la resección de dicha lesión metastásica es la primera recomendación la cual parece mejorar la sobrevida, seguida de terapia sistémica paliativa.

Introduction: Krukenberg tumor is metastatic and it accounts for 1 percent to 2 percent of ovarian tumors. Stomach is the most common primary location in 70 percent of cases, followed by colon, appendix, and breast. The prognosis is poor and its evolution is rapid. Objective: to describe a case of a patient with Krukenberg tumor.Case presentation: a 53 year old woman was consulted due to menopausal bleeding in stains and lower abdomen pain. She had personal history of gastric carcinoma, gallstones, breast nodule and hypertension. Gynecologic sonographic study was performed with positive tumor markers for ovarian cancer and negative tumor markers.Results: intraoperative finding: fibroid uterus and both ovaries were loculate, smooth surface coating of mucinous content with solid areas of color and adverse heterogeneous consistency was observed. Hysterectomy with oophorectomy was performed.Conclusions: Krukenberg, metastatic ovarian tumor is a rare entity with poor prognosis after diagnosis. Still, resection of the metastatic lesion is the first recommendation which appears to improve survival, followed by palliative systemic therapy.

Gastric Cancer Presenting as a Krukenberg Tumor at 22 Weeks' Gestation

Gastric cancer is rare during pregnancy, and often advanced upon presentation. A Krukenberg tumor presents a diagnostic and therapeutic challenge in the pregnant patient. We present a case of a 38-year-old woman at 22 weeks' gestation who presented with worsening epigastric pain, and was found to have a left pelvic mass on ultrasound, which was confirmed by magnetic resonance imaging. She went into active labor and delivered a viable infant via vaginal delivery. An exploratory laparotomy revealed a large mass originating from her left ovary and diffuse thickening of the lesser curvature of the stomach. Frozen section investigation revealed the presence of signet cell adenocarcinoma. Subsequent upper endoscopy showed linitis plastica, while biopsy confirmed the presence of adenocarcinoma. In conclusion, the occurrence of gastric cancer in pregnancy is rare despite extremely common symptoms. The management poses a challenge because of the need for early treatment, and the continuation of the pregnancy.

Fibroma ovárico con células estromales en anillo de sello: un tumor extremadamente infrecuente: diagnóstico diferencial del tumor de Krukenberg / Ovarian fibroma with stromal signet-ring cells: differential diagnosis of Krukenberg tumor

La presencia de "células en anillo de sello" en el tejido ovárico es el marcador histológico clásico del tumor de Krukenberg. Un adenocarcinoma metastásico altamente agresivo y de baja sobrevida. En cambio, los fibromas ováricos son tumores del estroma generalmente benignos. Presentamos un caso muy infrecuente de fibroma celular con presencia de células en anillo de sello y revisamos los criterios para el diagnóstico diferencial con el tumor de Krukenberg.

The presence of signet-ring cells in ovarian tissue is classically described as histological marker of Krukenberg tumor. It is highly aggressive metastatic adenocarcinoma with low survival. In contrast, ovarian fibroid is a stromal tumor usually benign. We present a very rare case of cellular fibroma with presence of signet-ring cells and we review the criteria for differential diagnosis of Krukenberg tumor.

Friedrich Krukenberg, el del tumor de Krukenberg: a propósito de una serie de casos / Friedrich Krukenberg of Krukenberg's Tumor: Report of a series of cases

El tumor de Krukenberg (descrito por un médico alemán que tenía el mismo nombre) es un tumor de ovario que representa la metástasis de una tumoración primaria usualmente ubicada en el estómago. En este trabajo se realiza una breve reseña histórica y se presentan cinco casos manejados en nuestro servicio, con el fin de mostrar la complejidad de su diagnóstico, el abordaje terapéutico y el pésimo pronóstico que esta enfermedad tiene.

Krukenberg's tumor is an ovarian tumor first described by the German physician Friedrich Krukenberg. It is a metastasis of a primary tumor which is usually located in the stomach. This article presents a brief overview of the history of these tumors and a series of 5 cases which were handled in our service. The aim of this article is to demonstrate the complexity of this diagnosis, the therapeutic approach, and the pessimistic prognosis that this condition has.

Adenocarcinoma mucoproductor de colon con infiltración de estómago y metástasis ováricas (tumor de Krukenberg) / Colon mucoproducing adenocarcinoma with stomach infiltration and ovarian metastases (Krukenberg's tumor)

Se presenta una paciente femenina de 29 años, operada de urgencia por presentar un gran tumor que incluía cuerpo gástrico y colon trasverso, con una perforación gástrica. Se realizó una gastrectomía subtotal con colectomía trasversa en bloque que incluyó el epiplón mayor. El diagnóstico histológico fue adenocarcinoma túbulo papilar mucoproductor de origen colónico, que infiltra hasta la serosa y pared gástrica. Se realizó tratamiento adyuvante con poliquimioterapia. Diez meses después presenta un tumor en hipogastrio, que al tacto vaginal, correspondía a los órganos genitales, sospecha clínica que confirman el ultrasonido abdominal y la tomografía axial computarizada. El hallazgo transoperatorio fueron tumores voluminosos de ambos ovarios, y otro tumor que afectaba la unión rectosigmoide. Se realizó una histerectomía radical con ooforectomía bilateral y sigmoidectomía, se reseca la porción proximal del recto, y se cierra tipo Hartman. El diagnóstico histológico final fue metástasis en serosa uterina e intestinal, y en ambos ovarios de adenocarcinoma mucoproductor, túbulo papilar de intestino previamente diagnosticado (tumor de Krukenberg). Se complementó el tratamiento con poliquimioterapia adyuvante(AU)

This is the case of a woman aged 29 operated on of emergency due to a tumor involving gastric body and transverse colon with gastric perforation. A subtotal gastrectomy with block transverse colectomy including the greater omentum was carried out. The histological diagnosis was a mucoproducing papillary tubular adenocarcinoma of colonic origin infiltrating to serosa and gastric wall. An adjuvant treatment was applied with poly-chemotherapy. Ten months later appears a hypogastric tumor which at vaginal manual examination corresponding to genital organs, clinical suspicion confirmed by abdominal ultrasound and computerized axial tomography. The transoperative findings were bulky tumors of both ovaries and another tumor involving the rectosigmoid joint. A radical hysterectomy with bilateral oophorectomy and sigmoidectomy was carried out with resection of proximal rectal portion with type Hartman closure. The final histological diagnosis was a metastasis in uterine and intestinal serosa and in both ovaries a mucoproducing adenocarcinoma, previous papillary tubule was also diagnosed (Krukenberg's tumor). Treatment was applied using adjuvant poly-chemotherapy(AU)

Tumor de Krukenberg / Krunkenberg's tumor

El tumor de Krukenberg supone el 30-40 por ciento de los cánceres metastásicos al ovario y el 1-2 por ciento de todos los tumores malignos de ovario. En la actualidad, y pese a que el concepto de tumor de Krukenberg ha sido usado para referirse a todos los tumores metastásicos del ovario, se consideran como tal a los que tienen un origen digestivo. Su pronóstico es malo con raras supervivencias más allá del año. Se presenta un caso de una paciente femenina de 38 años de edad, que ingresa por ascitis moderada, anorexia y pérdida de peso, a la cual se le realizó una laparotomía con el posible diagnóstico de un proceso oncoproliferativo del ovario y el diagnóstico histopatológico arrojó un tumor de Krukenberg

Krukenberg's tumor accounts for 30-40 percent of ovarian metastatic cancer and for the 1-2 percent of all ovarian malignant tumors. Nowadays and in spite of the fact that the concept of Krukenberg' tumor has been used to refer to all ovarian metastatic tumors those with a digestive origin, its prognosis if bad with only a few survivals beyond one year. This is the case of a female patient aged 38 admitted due to a moderate ascites, anorexia and lose weight undergoes laparotomy with the possible diagnosis of a oncoproliferous ovarian process and the histopathological diagnosis showed a Krukenberg's tumor

Metachronous Ovarian Metastases Following Resection of the Primary Gastric Cancer

PURPOSE: We performed this study to evaluate the clinical presentation as well as the proper surgical intervention for ovarian metastasis from gastric cancers and these tumors were identified during postoperative follow-up. This will help establish the optimal strategy for improving the survival of patients with this entity. MATERIALS AND METHODS: 22 patients (3.2%) with ovarian metastasis were noted when performing a retrospective chart review of (693) females patients who had undergone a resection for gastric cancer between 1981 and 2008. The covariates used for the survival analysis were the patient age at the time of ovarian relapse, the size of the tumor, the initial TNM stage of the gastric cancer, the interval to metastasis and the presence of gross residual disease after treatment for Krukenberg tumor. The cumulative survival curves for the patient groups were calculated with the Kaplan-Meier method and they were compared by means of the Log-Rank test. RESULTS: The average age of the patients was 48.6 years (range: 24 to 78 years) and the average survival time of the 22 patients was 18.8 months (the estimated 3-year survival rate was 15.8%) with a range of 2 to 59 months after the diagnosis of Krukenberg tumor. The survival rate for patients without gross residual disease was longer than that of the patients with gross residual disease (P=0.0003). In contrast, patient age, the size of ovarian tumor, the initial stage of gastric adenocarcinoma, the interval to metastasis and adjuvant chemotherapy were not prognostic indicators for survival after the development of ovarian metastasis. CONCLUSIONS: Early diagnosis and complete resection are the only possible hope to improve survival. As the 3-year survival rate after resection of Krukenberg tumor is 15.8%, it seems worthwhile to consider performing tumorectomy as the second cytoreduction.

Utility of Surgical Resection in the Management of Metachronous Krukenberg's Tumors of Gastric Origin

PURPOSE: The aim of this study was to determine the prognostic factors and the significance of metastatectomy for Krukenberg's tumors of gastric origin. MATERIALS AND METHODS: Among the patient who underwent gastric surgery from 1992 through 2005, 90 female patients with Krukenberg's tumors of gastric origin were identified. We retrospectively reviewed the clinicopathologic characteristics, prognostic factors, and treatments for primary gastric cancer. We also investigated the prognostic risk factors for the onset of metachronous Krukenberg's tumors and the survival time of patients who underwent an operation for metachronous Krukenberg's tumors. RESULTS: The presence of a synchronous Krukenberg's tumor (mean survival time=17.6 months, P<0.01), peritoneal seeding (14.5 months, P<0.01), and non-curative resection (15.1 months, P<0.01), were statistically significant prognostic factors for survival time in female patients with gastric cancer. The stage of primary gastric cancer (P=0.049) and lymph node metastasis (P=0.011) were statistically significant risk factors for recurrence time of a metachronous Krukenberg's tumor. In the metachronous Krukenberg's tumor group (n=53), the mean survival time of the metastatectomy group (n=46, 43.2 months, P=0.012) was longer than that in the chemotherapy or conservative treatment groups (n=7 and 24 months, respectively). Metastatectomy, presense or abscence of residual tumor and extent of residual tumor were significant prognostic factors for survival time in female patients with metachronous Krukenberg's tumor of gastric origin. CONCLUSIONS: A close observation and evaluation with ultrasound or computed tomography is necessary in female patients with advanced gastric cancer to detect a metachronous Krukenberg's tumor as soon as possible. The surgeon must operate more aggressively in patients with metachronous Krukenberg's tumors.

Krukenberg tumor in a teenager mimicking advanced ovarian cancer: Case report / 대한산부인과학회지

We experienced a case of Krukenberg tumor arising from transverse colon in a teenager who complained acute abdominal pain, which was confirmed by postoperative pathologic study and initially misdiagnosed as ovarian cancer with a huge pelvic mass, and report with a brief review of literatures.

Krukenberg Tumor Confirmed by Surgery during the Follow-up after a Primary Resection of Colorectal Cancer

PURPOSE: We performed this study to evaluate the clinical presentation of, as well as the surgical intervention for, ovarian metastasis from colorectal cancers identified during postoperative follow-up. METHODS: Twelve cases (2.4%) of ovarian metastasis were observed among retrospective chart review of 493 females patients who underwent a resection of colorectal cancer between 1981 and 2006. The covariates used for the survival analysis were patient age at the time of ovarian relapse, size of the tumor, initial TMN stage of the colon cancer, the interval to metastasis, and the presence of gross residual disease after treatment for a Krukenberg tumor. The cumulative survival curves for the patient groups were calculated with the Kaplan-Meier method and were compared by means of the Log-Rank test. RESULTS: The average age of the patients was 48.9 years, ranging from 24 to 71 years, and the average survival time of the 12 patients was 19.6 months (estimated 3-year survival rate was 16.7%), with a range of 3 to 59 months after the diagnosis of a Krukenberg tumor. The survival rate for patients without gross residual disease was longer than that of patients with gross residual disease (P=0.0003). In contrast, patient age, size of the ovarian tumor, initial stage of the colon adenocarcinoma, and interval to metastasis were not prognostic indicators for survival after the development of ovarian metastasis. CONCLUSIONS: Our results suggest that, in general, most cases with ovarian metastasis have poor prognosis and that the absence of residual disease after treatment is a favorable prognostic factor in cases of a Krukenberg tumor of colon origin.

A case of krukenberg tumor / 대한산부인과학회지

Metastatic tumor to ovary are uncommon, but there is a situation in which a metastatic adenocarcinoma to ovary appears as a large mass and resembles a primary tumor: a Krukenberg tumor of ovary which has a signet ring histologic pattern and usually is metastatic principally from a gastrointestinal tract cancer. We have an experience of one case of metastatic Krukenberg tumor from stomach and report the case with brief review of literature.
