RESUMO
BACKGROUND: Recurrent cervical cancer is a life-threatening disease, with limited treatment options available when disease progression occurs after first-line combination therapy. METHODS: We conducted a phase 3, multinational, open-label trial of tisotumab vedotin as second- or third-line therapy in patients with recurrent or metastatic cervical cancer. Patients were randomly assigned, in a 1:1 ratio, to receive tisotumab vedotin monotherapy (2.0 mg per kilogram of body weight every 3 weeks) or the investigator's choice of chemotherapy (topotecan, vinorelbine, gemcitabine, irinotecan, or pemetrexed). The primary end point was overall survival. RESULTS: A total of 502 patients underwent randomization (253 were assigned to the tisotumab vedotin group and 249 to the chemotherapy group); the groups were similar with respect to demographic and disease characteristics. The median overall survival was significantly longer in the tisotumab vedotin group than in the chemotherapy group (11.5 months [95% confidence interval {CI}, 9.8 to 14.9] vs. 9.5 months [95% CI, 7.9 to 10.7]), results that represented a 30% lower risk of death with tisotumab vedotin than with chemotherapy (hazard ratio, 0.70; 95% CI, 0.54 to 0.89; two-sided P = 0.004). The median progression-free survival was 4.2 months (95% CI, 4.0 to 4.4) with tisotumab vedotin and 2.9 months (95% CI, 2.6 to 3.1) with chemotherapy (hazard ratio, 0.67; 95% CI, 0.54 to 0.82; two-sided P<0.001). The confirmed objective response rate was 17.8% in the tisotumab vedotin group and 5.2% in the chemotherapy group (odds ratio, 4.0; 95% CI, 2.1 to 7.6; two-sided P<0.001). A total of 98.4% of patients in the tisotumab vedotin group and 99.2% in the chemotherapy group had at least one adverse event that occurred during the treatment period (defined as the period from day 1 of dose 1 until 30 days after the last dose); grade 3 or greater events occurred in 52.0% and 62.3%, respectively. A total of 14.8% of patients stopped tisotumab vedotin treatment because of toxic effects. CONCLUSIONS: In patients with recurrent cervical cancer, second- or third-line treatment with tisotumab vedotin resulted in significantly greater efficacy than chemotherapy.

BACKGROUND: At the time of AtTEnd trial design, standard treatment for advanced or recurrent endometrial cancer included carboplatin and paclitaxel chemotherapy. This trial assessed whether combining atezolizumab with chemotherapy might improve outcomes in this population. METHODS: AtTEnd was a multicentre, double-blind, randomised, placebo-controlled, phase 3 trial done in 89 hospitals in 11 countries across Europe, Australia, New Zealand, and Asia. Enrolled patients were aged 18 years or older, and had advanced or recurrent endometrial carcinoma or carcinosarcoma, an Eastern Cooperative Oncology Group performance status of 0-2, and received no previous systemic chemotherapy for recurrence. Patients were randomly assigned (2:1) using an interactive web response system (block size of six) to either atezolizumab 1200 mg or placebo given intravenously with chemotherapy (carboplatin at area under the curve of 5 or 6 and paclitaxel 175 mg/m2 intravenously on day 1 every 21 days) for 6-8 cycles, then continued until progression. Stratification factors were country, histological subtype, advanced or recurrent status, and mismatch repair (MMR) status. Participants and treating clinicians were masked to group allocation. The hierarchically tested co-primary endpoints were progression-free survival (in patients with MMR-deficient [dMMR] tumours, and in the overall population) and overall survival (in the overall population). Primary analyses were done in the intention-to-treat population, defined as all randomly assigned patients who gave their full consent to participation in the study and data processing. Safety was assessed in all patients included in the intention-to-treat population who received at least one dose of study treatment. Here, we report the primary progression-free survival and the interim overall survival results. This study is ongoing and is registered with ClinicalTrials.gov, NCT03603184. FINDINGS: Between Oct 3, 2018, and Jan 7, 2022, 551 patients were randomly assigned to atezolizumab (n=362) or placebo (n=189). Two patients in the atezolizumab group were excluded from all analyses due to lack of consent. Median follow-up was 28·3 months (IQR 21·2-37·6). 81 (23%) patients in the atezolizumab group and 44 (23%) patients in the placebo group had dMMR disease by central assessment. In the dMMR population, median progression-free survival was not estimable (95% CI 12·4 months-not estimable [NE]) in the atezolizumab group and 6·9 months (6·3-10·1) in the placebo group (hazard ratio [HR] 0·36, 95% CI 0·23-0·57; p=0·0005). In the overall population, median progression-free survival was 10·1 months (95% CI 9·5-12·3) in the atezolizumab group and 8·9 months (8·1-9·6) in the placebo group (HR 0·74, 95% CI 0·61-0·91; p=0·022). Median overall survival was 38·7 months (95% CI 30·6-NE) in the atezolizumab group and 30·2 months (25·0-37·2) in the placebo group (HR 0·82, 95% CI 0·63-1·07; log-rank p=0·048). The p value for the interim analysis of overall survival did not cross the stopping boundary; therefore, the trial will continue until the required number of events are recorded. The most common grade 3-4 adverse events were neutropenia (97 [27%] of 356 patients in the atezolizumab group vs 51 [28%] of 185 in the placebo group) and anaemia (49 [14%] vs 24 [13%]). Treatment-related serious adverse events occurred in 46 (13%) patients in the atezolizumab group and six (3%) patients in the placebo group. Treatment-related deaths occurred in two patients (pneumonia in one patient in each group). INTERPRETATION: Atezolizumab plus chemotherapy increased progression-free survival in patients with advanced or recurrent endometrial carcinoma, particularly in those with dMMR carcinomas, suggesting the addition of atezolizumab to standard chemotherapy as first-line treatment in this specific subgroup. FUNDING: F Hoffmann-La Roche.
RESUMO
PURPOSE: Everolimus in combination with endocrine therapy (ET) was formerly approved as 2nd-line therapy in HR(+)/HER2(-) advanced breast cancer (aBC) patients (pts) progressing during or after a non-steroidal aromatase inhibitor (NSAI). Since this approval, the treatment landscape of aBC has changed dramatically, particularly with the arrival of CDK 4-6 inhibitors. Endocrine monotherapy after progression to CDK4/6 inhibitors has shown a limited progression-free survival (PFS), below 3 months. Evidence of the efficacy of everolimus plus ET after CDK4/6 inhibitors is scarce. METHODS: A retrospective observational study of patients with aBC treated with everolimus and ET beyond CDK4/6-i progression compiled from February 2015 to December 2022 in 4 Spanish hospitals was performed. Clinical and demographic data were collected from medical records. The main objective was to estimate the median progression-free survival (mPFS). Everolimus adverse events (AE) were registered. Quantitative variables were summarized with medians; qualitative variables with proportions and the Kaplan-Meier method were used for survival estimates. RESULTS: One hundred sixty-one patients received everolimus plus ET (exemestane: 96, fulvestrant: 54, tamoxifen: 10, unknown: 1) after progressing on a CDK4/6 inhibitor. The median follow-up time was 15 months (interquartile range: 1-56 months). The median age at diagnosis was 49 years (range: 35-90 years). The estimated mPFS was 6.0 months (95%CI 5.3-7.8 months). PFS was longer in patients with previous CDK4/6 inhibitor therapy lasting for > 18 months (8.7 months, 95%CI 6.6-11.3 months), in patients w/o visceral metastases (8.0 months, 95%CI 5.8-10.5 months), and chemotherapy-naïve in the metastatic setting (7.2 months, 95%CI 5.9-8.4 months). CONCLUSION: This retrospective analysis cohort of everolimus plus ET in mBC patients previously treated with a CDK4/6 inhibitor suggests a longer estimated mPFS when compared with the mPFS with ET monotherapy obtained from current randomized clinical data. Everolimus plus ET may be considered as a valid control arm in novel clinical trial designs.

OBJECTIVE: In the PAOLA-1/ENGOT-ov25 trial (NCT02477644), adding maintenance olaparib to bevacizumab provided a substantial progression-free survival benefit in patients with newly diagnosed advanced ovarian cancer and homologous recombination deficiency (HRD)-positive tumors, irrespective of clinical risk. Subsequently, a clinically meaningful improvement in overall survival was reported with olaparib plus bevacizumab in the HRD-positive subgroup. We report updated progression-free survival and overall survival by clinical risk and HRD status. METHODS: Patients in clinical response after first-line platinum-based chemotherapy plus bevacizumab received maintenance olaparib (up to 24 months) plus bevacizumab (up to 15 months in total) or placebo plus bevacizumab. This post hoc analysis evaluated 5-year progression-free survival and mature overall survival in patients classified by clinical risk and HRD status. RESULTS: Of 806 randomized patients, 74% were higher-risk and 26% were lower-risk. In higher-risk HRD-positive patients, the hazard ratio (HR) for progression-free survival was 0.46 (95% confidence interval (95% CI) 0.34 to 0.61), with 5-year progression-free survival of 35% with olaparib plus bevacizumab versus 15% with bevacizumab alone; and the HR for overall survival was 0.70 (95% CI 0.50 to 1.00), with 5-year overall survival of 55% versus 42%, respectively. In lower-risk HRD-positive patients, the HR for progression-free survival was 0.26 (95% CI 0.15 to 0.45), with 5-year progression-free survival of 72% with olaparib plus bevacizumab versus 28% with bevacizumab alone; and the HR for overall survival was 0.31 (95% CI 0.14 to 0.66), with 5-year overall survival of 88% versus 61%, respectively. No benefit was seen in HRD-negative patients regardless of clinical risk. CONCLUSION: This post hoc analysis indicates that in patients with newly diagnosed advanced HRD-positive ovarian cancer, maintenance olaparib plus bevacizumab should not be limited to those considered at higher risk of disease progression. Five-year progression-free survival rates support long-term remission and suggest an increased potential for cure with particular benefit suggested in lower-risk HRD-positive patients.

Olaparib, a poly(ADP-ribose) polymerase inhibitor, in combination with the antiangiogenic agent bevacizumab, is approved as maintenance therapy for patients with newly diagnosed stage III or IV epithelial ovarian cancer who have homologous recombination deficient tumors with a deleterious or suspected deleterious BRCA mutation and/or genomic instability based on the long-lasting survival benefit observed in the PAOLA-1 trial. Despite treatment with olaparib and bevacizumab showing an acceptable safety profile, the rate of discontinuations due to adverse events was relatively high, and toxicity related to this regimen may restrict its clinical use. Proper management of olaparib/bevacizumab-related adverse events is important for the improvement of quality of life and maximization of the efficacy of maintenance therapy. Here, we summarize the safety results of the PAOLA-1 study, focusing on treatment discontinuation reasons and adverse event profiles. We sought to shed light on toxicity monitoring and prevention, providing concise recommendations for the clinical management of the most relevant side effects.

RESUMEN Fundamento: los tumores de células granulares son lesiones benignas infrecuentes de crecimiento lento que pueden aparecer en cualquier sitio del organismo. La región de cabeza y cuello incluye las localizaciones más frecuentes (entre el 30 y el 50 % de todos los tumores de este tipo, hasta los del sistema nervioso central). Objetivo: presentar un caso de tumor de células granulares intratiroideo. Caso clínico: se presenta el caso de una paciente femenina de 37 años de edad con enfermedad nodular de la glándula tiroides de crecimiento lento con escasa sintomatología, con confirmación histológica tumor de células de la granulosa. Al examen físico se identificó aumento de volumen en la región anterolateral del cuello, en relación con el lóbulo derecho de la glándula tiroidea, que correspondía con lesión tumoral de 3 cm, mal delimitada, adherida a planos profundos, no dolorosa a la palpación. En la ecografía se observó: lóbulo derecho del tiroides de 4,3 cm x 1,2 cm x 1,4 cm, no homogéneo con lesión nodular de 2,8 x 1,4 cm mal delimitada, de bordes irregulares. Se realizó biopsia transoperatoria que se reportó como positiva de células neoplásicas malignas, sin embargo, el estudio histológico extemporáneo reveló un tumor benigno de células granulares intratiroideo. El tratamiento quirúrgico es curativo en este caso. Conclusiones: el diagnóstico de tumor de células granulares intratiroideo benigno, se presenta con las características de una lesión tumoral maligna, debe tenerse en cuenta en el diagnóstico diferencial de los tumores de la glándula tiroides.
ABSTRACT Background: the granular cells tumors are uncommon benign lesions of slow growth that can appear in any place of the organism. The head and neck region includes the most frequent localizations (between the 30 and 50% of all the tumors of this type, including those of the central nervous system). Objective: to present a case of intra-thyroid granular cell tumor. Clinical case: a case of a 37 year-old female patient with nodular illness of the thyroid of slow growth with scarce symptoms, with histologic confirmation of granular cells tumor is presented. To the physical exam, an increase of volume was identified in the anterolateral region of the neck, in connection with the right lobe of the thyroid gland that corresponded with a tumoral lesion of 3cm approximately, not well defined, stuck to deep planes, not painful to the palpation. In the echography, it was observed: right lobe of the thyroid of 4.3 cm x 1.2cm x 1.4 cm, not homogeneous with a nodular lesion of 2.8 x 1.4 cm not well defined, of irregular borders. During the surgery, a frozen section was examined and reported as positive of malignancy, however, the untimely histologic study revealed a benign intra-thyroid granular cell tumor. The surgical treatment is healing in this case. Conclusions: the diagnosis of intra-thyroid benign granular cell tumor is presented with the characteristics of a malign tumor, it should be kept in mind in the differential diagnosis of the tumors of the thyroid.

RESUMO
Se realizó una revisión de la literatura sobre la historia de la Anatomía Patológica, que incluyó la búsqueda por INTERNET de un gran número de bibliografías que abordaran su evolución histórica, principales figuras, diferentes métodos de estudio, en el mundo y en nuestro país, con la finalidad de conocer, ampliar y contribuir a divulgar los conocimientos al respecto. Se encontró que la patología puede dividirse para su estudio en diferentes períodos, correspondiéndose con el desarrollo y la evolución del hombre a través de la historia universal, transitando por el surgimiento de la Anatomía Patológica, el advenimiento del microscopio, surgimiento de la patología celular, la patología quirúrgica, hasta llegar a los orígenes de las ciencias patológicas en Cuba y su desarrollo en el siglo XIX, XX y el período posterior a 1959. Se acompañan los textos de 11 imágenes correspondientes a los diferentes protagonistas históricos u obras de trascendencia. Resaltamos el respaldo alcanzado por la especialidad a partir del triunfo revolucionario, que ha permitido el desarrollo tecnológico de los profesionales del sector en el país, en beneficio del diagnóstico a las afecciones de los pacientes.
A review of the literature about the history of the Pathologic Anatomy, was carried out, that included the search by INTERNET of a great number of bibliographies that approach its historical evolution, main figures, different study methods in the world and in our country, with the purpose to know, to further and to contribute to make public the knowledge on the matter. It was found that pathology may be divided for its study in different periods, which correspond with the development and man evolution through the universal history, traveling for the arise of the Pathologic Anatomy, the arrival of the microscope, the arise of the cellular and surgical pathology, until to arrive at the origins of the pathological sciences in Cuba and its development in the XIX, XX centuries, and in the period after 1959. The texts of 11 images pertaining to different historical protagonists or significance works are accompanied. We stand out the support reached by the specialty departing from the revolutionary triumph, that has permitted the technological development of the professionals of the sector in the country, for the benefit of the diagnosis to the affections of patients.
RESUMO
En Cuba los tumores y quistes de ovario en la infancia ocupan aproximadamente el 1 por ciento de todos los procesos tumorales, durante esta etapa de la vida, más del 50 por ciento de estos tumores corresponden como quistes simples, teratomas benignos, y quistes foliculares, por lo que se realizó un estudio retrospectivo longitudinal en niños con incidencias de estos tumores en el Hospital Pediátrico Eduardo Agramonte Piña, Camagüey, desde julio de 1973 a julio de 2004, con el objetivo de valorar la incidencia de estos tumores en niños. El universo y muestra lo constituyeron los 170 pacientes ingresados por dicha enfermedad. Se revisaron las historias clínicas de los enfermos. Se confeccionó un formulario que incluyó variables como. la edad, la forma de presentación, el lado más afecto, el histología, los complementarios realizados y las complicaciones, donde predominó el rango de edad entre los 11y15 años con 122 pacientes para un 71.8 por ciento. Existió un aumento de la incidencia en el ovario derecho para un 71.8 por ciento.
