Paraneoplastic acquired hemophilia A associated with hilar cholangiocarcinoma arising in an intraductal papillary neoplasm of the bile duct / Paraneoplásico adquirido hemofilia A asociada con colangiocarcinoma hiliar que surge en un papilar intraductal neoplasia del conducto biliar

A 74-year-old female was admitted for painless jaundice. Laboratory tests showed hyperbilirubinemia, cholestasis, normal coagulation, and Ca19-9:163U/L. The CT-scan reported dilation of the intrahepatic and extrahepatic bile ducts secondary to a 24mm tumor in the intrapancreatic common bile duct. The magnetic cholangioresonance showed multiple endoluminal polypoid lesions, suggestive of intraductal papillary neoplasm of the bile duct (IPNB). The endoscopic bile duct brushing was non-conclusive.(AU)

Lytic bone lesion as the first manifestation of late recurrence of gastric cancer.

The incidence of gastric cancer has declined worldwide, it is the second most common cancer worldwide and two thirds of these occurs in developing countries. In Peru, this neoplasm, has one of the highest incidence and mortality rates. The main sites of gastric adenocarcinoma metastasis are the liver and lung; In contrast, bone metastasis are an uncommon finding up to 0.9 to 2% of patients and is associated with an ominous prognosis. We present the case of a 48-year-old female patient diagnosed with gastric cancer treated surgically and with regular controls. 5 years later, she was admitted due to pain in the left knee and increased volume. Knee radiographs reported a lytic lesion in the medial condyle and distal diaphysis of the left femur, with soft tissue involvement, wide transition zone, cortical rupture. Bone scintigraphy described bone oligo metastatic disease. Extension studies were negative for visceral metastasis. Palliative biopsy and curettage of the femur lesion was performed; the pathology was consistent with gastric adenocarcinoma metastasis.

Impact of cancer awareness campaigns in Peru: a 5-year Google Trends analysis.

Background: The aim of this research was to characterise the interest on the most frequent cancers in Peru through Google Trends, its geographic and temporal relationship with massive awareness campaigns. Methods: A temporal trends analysis for the last 5 years was carried out, comparing the Relative Search Volume (RSV) with the dates of mass cancer awareness campaigns in Peru. Google Trends application was used to evaluate the interest in the topics: breast, prostate, cervical stomach and colorectal cancer between 1 January 2016 and 31 December 2020, expressed in RSV. The annual RSV for each neoplasm was compared, as well as its annual variation using the Kruskal-Wallis test. The correlation between the RSV and the estimated incidence for each province was measured using the Spearman test. Results: The topics with the highest RSV were breast (median: 20, range: 6-100) and prostate cancer (median: 28, range: 9-48). The topic 'breast cancer' showed a cyclical punctual increase in October, its awareness month. Searches for cervical, stomach and colorectal cancer were smaller and did not show peaks of interest. It was observed that the RSV was variable when compared with previous years (p < 0.05 for all the evaluated topics). Geographically, different provincial configurations of interest were observed according to neoplasia. When correlating the RSV with the incidence by province, a non-significant positive correlation (p > 0.05) was found for breast, cervical and colorectal cancer. Conclusions: This study suggests a positive temporal correlation between RSV and awareness cancer campaigns in Peru specially to breast cancer and, to a lesser extent, prostate cancer. Significant variations of interest were demonstrated for each neoplasm among the evaluated years. No significant correlation was found between the incidence rate and the average RSV among Peruvian provinces.

Gastric myeloid sarcoma: A case report.

BACKGROUND: Myeloid sarcoma (MS) is a rare hematologic malignancy defined as an extramedullary tumor of immature granulocytic cells. It can occur as primary or de novo and be associated with myelodysplasia or myeloproliferative neoplasms. The most frequent locations are the skin, lymph nodes and bones. The case of a patient with a diagnosis of primary granulocytic de novo gastric MS is reported. CASE SUMMARY: A 19-year-old female patient with MS, whose abdominal computed tomography showed a bulky tumor of 16.5 cm in the gastric chamber with infiltration in the retroperitoneal, pancreatic and bile duct region; the histological study showed gastric mucosa diffusely infiltrated by mononucleated cells and the immunohistochemistry expressed myeloperoxidase. After receiving induction chemotherapy based on the 3 + 7 regimen (daunorubicin/cytarabine), the patient developed severe hematological toxicity and neutropenic typhlitis which required a prolonged medical treatment. She presented a rapid disease progression. Although she received supportive treatment, the patient died. CONCLUSION: Gastric primary de novo MS is a rare and aggressive course neoplasm, fostering knowledge is very important to decide its management and to promote more approaches focused on understanding this pathology and its particularities in our population.

[Pathological complete response after multimodal treatment of adult Ewing sarcoma]. / Respuesta patológica completa al tratamiento multimodal en sarcoma de Ewing del adulto.

Ewing sarcoma is a rare and highly aggressive neoplasm that occurs most frequently in male adolescents. The incorporation of neoadjuvant therapy and new surgical techniques has improved survival. We present the case of a 41-year-old man diagnosed with Ewing sarcoma of the chest wall, whose tumor showed a pathological complete response to a multimodal treatment consisting of concurrent chemotherapy, radiotherapy, and surgical resection. Ewing sarcoma rarely occurs in adults, who generally have a worse prognosis. A multimodal approach for the treatment of patients older than 40 years has proven to improve oncological results.

Calcitonin negative neuroendocrine thyroid carcinoma: Case report and literature review

SUMMARY Medullary thyroid carcinoma (MTC) is a relatively rare neuroendocrine tumor that originates in the parafollicular C cells of the thyroid gland. It is characterized by the synthesis and secretion of calcitonin. Usually, serum calcitonin is used as part of the diagnosis and follow-up of these patients. Few cases of MTC with negative calcitonin have been reported worldwide, whose diagnosis is a clinical challenge.

El carcinoma medular de tiroides (MTC) es un tumor neuroendocrino relativamente raro que se origina en las células C para foliculares de la glándula tiroides. Se caracteriza por la síntesis y secreción de calcitonina. Por lo general, la calcitonina sérica se utiliza como parte del diagnóstico y seguimiento de estos pacientes. Se han notificado pocos casos de MTC con calcitonina negativa en todo el mundo, cuyo diagnóstico es un desafío clínico.

Sarcoma Sinovial De Pene: Hallazgos Clínico Radiológicos / Penile Synovial Sarcoma: Clinical and Radiological findings

Varón de 22 años, se presentó con una tumoración de consistencia dura, de 8 cm, dependiente de base del pene de 6 meses de evolución, cuya biopsia fue compatible con sarcoma sinovial (Figura 1). La resonancia magnética (RM) mostró una tumoración que compromete la base del pene, pilar izquierdo y parcialmente el pilar derecho, se extiende hacia los 2/3 distales, sin descartar infiltración uretral (Figura 1).

A 22-year-old man presented with a 6-month-old 8 cm hard tumor at the base of the penis, whose biopsy was consistent with synovial sarcoma (Figure 1). The magnetic resonance imaging (MRI) showed a tumor that compromises the base of the penis, the left pillar and partially the right pillar, extending to the distal 2/3, without ruling out urethral infiltration (Figure 1).

Intrathyroidal thymic carcinoma misdiagnosed as a medullary thyroid carcinoma.

The intrathyroidal thymic carcinoma is a rare neoplasm. The probable origin of this neoplasm is the presence of ectopic thymic tissue or remnants of the third and fourth branchial arch. The case of a 49-year-old female with an initial diagnosis of medullary thyroid cancer is presented. When she was operated for regional recurrence, 16 years later, the pathology report demonstrates the presence of a intrathyroidal thymic carcinoma. Intrathyroidal thymic carcinoma is considered an independent type of thyroid carcinoma because this entity has specific clinical-pathological characteristics similar to thymic carcinomas and different prognosis than known thyroid carcinomas. We present the case of a patient initially treated as having a medullary thyroid carcinoma who, upon presenting recurrence, the presence of intrathyroidal thymic carcinoma was demonstrated.

El carcinoma tímico intratiroideo es una neoplasia rara. El origen probable de esta neoplasia es la presencia de tejido tímico ectópico o de restos del tercer y cuarto arcos branquiales. Se presenta el caso de una mujer de 49 años con diagnóstico inicial de cáncer medular de tiroides. Cuando fue operada por recurrencia regional, 16 años después, se demostró la presencia de un carcinoma tímico intratiroideo, que se considera un tipo independiente de carcinoma tiroideo debido a que tiene características clínico-patológicas específicas similares a los carcinomas tímicos y un pronóstico diferente a los carcinomas de tiroides conocidos. Este caso se trató inicialmente como carcinoma medular de tiroides y al presentar recurrencia se demostró la presencia de un carcinoma tímico intratiroideo.

Cancer incidence and mortality trends in young adults in Metropolitan Lima young adults, 1990-2012.

AIMS: The purpose of this research was to calculate and compare standardised incidence and mortality ratios in young adults, based on the data published by the population-based cancer registry of Metropolitan Lima. METHOD: A secondary analysis was carried out on the data published by the population-based cancer registry of Metropolitan Lima in its last five volumes. Calculating the standardised incidence ratio, in accordance with the World Health Organization's standard population, was done using the direct method, and the annual percentage change was calculated using the Joinpoint Regression Program. RESULTS: From 1990 to 2012, 12,380 new cases of cancer in young adults between the ages of 20 and 49 were reported in Metropolitan Lima. The neoplasms with the highest standardised incidence ratio in the young adult male group were testicular cancer, brain and nervous system cancer, stomach cancer, non-Hodgkin's lymphoma and bowel cancer. The neoplasms with the highest standardised mortality ratio for this group were stomach cancer, brain and nervous system cancer, non-Hodgkin's lymphoma, tracheal cancer, bronchial and lung cancer and liver cancer. The neoplasms with the highest standardised incidence ratio in the young adult female group were breast cancer, cervical cancer, thyroid cancer, ovarian cancer and brain and nervous system cancer. The neoplasms with the highest standardised mortality ratio for this group were breast cancer, cervical cancer, stomach cancer, brain and nervous system cancer and non-Hodgkin's lymphoma. CONCLUSIONS: Young adults represent a highly unique group, characterised by little diagnostic suspicion, distribution and aggressiveness of the neoplasms that occur in them. Assessing and reporting incidence and mortality ratios in this age group can contribute to decision making.

Liver Resection as Part of Cytoreductive Surgery for Ovarian Cancer.

Objective: The aim of this study was to describe and evaluate the safety of hepatic resections for ovarian cancer liver metastases and the benefit in terms of survival as part of cytoreductive surgery among peritoneal seeding and parenchymal metastases. Materials and Methods: Data were reviewed retrospectively from patients who underwent liver resection as part of cytoreductive surgery for ovarian cancer at the Instituto Nacional de Enfermedades Neoplásicas, in Lima, Perú, from January 2009 to December 2017. Results: From January 2009 to December 2017, 1211 patients underwent surgical cytoreduction for ovarian cancer; 39 of these patients had liver resection as part of their surgical treatment, with 9, 17, and 13 patients receiving primary, secondary, and tertiary, resections, respectively. The mean age of the patients was 46, the majority (87%) had stage III/IV ovarian cancer. In addition, 21 patients had parenchymal metastasis resections, and 95% of the patients had Dindo-Clavien I and II grade complications. The 30-day mortality rate was 0. Conclusions: Liver resection for advanced ovarian cancer is a safe procedure for primary up to quaternary cytoreduction and may confer survival benefits to patients.

Introduction: Cervical cytology is the main tool for the detection and treatment of cervical cancer. Some studies carried out in the urban population have associated the realization and adherence with knowledge, attitudes and favorable practices of women with respect to this test. Objective: The aim of this study was to determine the level of knowledge, attitudes and practices towards cervical cytology in women of childbearing age in a rural Peruvian province. Material and Methods: A cross-sectional analytical study was conducted in a population of approximately 3148 women of childbearing age, a representative sample was obtained. An anonymous, validated, directed survey was used; it was applied by trained health personnel working in health centers of the primary care level in the districts of the province of Bolívar, La Libertad. Results: A total of 400 surveys were carried out. The results showed that 80 percent of the women surveyed had high and intermediate levels of knowledge, 70 percent had a favorable attitude, while 44 percent reported correct practices related to the cervical cytology test. The high and intermediate levels of knowledge were associated with age over 30 years (p: 0.02), married marital status (p: 0.05), the highest level of instruction (p: 0.00) and the use of contraceptive methods (p: 0.01); no relationship was found with the age of onset of sexual intercourse (p: 0.98). Conclusions: There is a high level of knowledge, attitudes and correct practices towards cervical cytology in the rural population of the province of Bolívar, but a low adherence to it(AU)
