Retrospective Analysis of All Types of Adjuvant Radiotherapy in Endometrial Cancer: Single-Center Experiences in a Middle-Income Country.

OBJECTIVE: We retrospectively analyzed the efficacy, focusing on overall survival (OS) and the patterns of failure, along with the toxicities of adjuvant radiotherapy (RT) in endometrial cancer patients. METHODS: Two-hundred and nineteen patients with endometrial cancer patients who received adjuvant radiotherapy ± adjuvant chemotherapy (ACT) from January 2014 to December 2018 were investigated for overall survival (OS), local recurrence-free survival rate (LRFS), regional recurrence-free survival rate (RRFS), and distant metastasis-free survival rate (DMFS). RESULT: Two-hundred and fourteen patients were evaluated. The numbers of VBT alone, EBRT plus VBT, and adjuvant chemotherapy (ACT) plus EBRT plus VBT were 65 (30.4%), 80 (37.4%), and 69 (32.2%) patients, respectively. Stage I (107 patients) was the most common followed by stage III (87 patients). With a median follow-up time of 67 months (IQR 56-78), the 5-year overall survival rates for VBT alone, EBRT plus VBT, and EBRT plus VBT plus ACT were 84.4%, 65%, and 57.4%, respectively. The most common severe (grade 3-4) acute toxicity was neutropenia (4.6%), followed by diarrhea (3.7%). Grade 3-4 late proctitis was found in only 1.9%. On multivariate analysis, advanced age (HR 6.15, p: 0.015), lymph node involvement (HR 6.66, p: 0.039), cervical involvement (HR 10.60, p: 0.029), and substantial LVSI (HR 21.46, p: 0.005) were associated with a higher risk of death. CONCLUSION: Advanced age (>65), substantial LVSI, lymph node involvement, and cervical stromal involvement were associated with poor overall survival. These findings here will help identifying high-risk patients and would make it possible to avoid unnecessary adjuvant treatment among patients with a good prognosis.

The morphometric study of parietal emissary foramen related with clinical implications in Thais / Estudio morfométrico del foramen emisario parietal relacionado con las implicaciones clínicas en tailandeses

SUMMARY: Parietal emissary foramina (PEF) are an important structure which the parietal emissary vein passes through. Aims of this study were to study morphometry of the PEF and its clinical implications. The present study examined in 800 parietal bones (400 Thai skulls; 200 males and 200 females). A total of 587 emissary foramina were found in 344 skulls. The PEF were found on the right side (298), left side (256). One hundred fifty-five unilateral, 189 bilateral, and 33 center of PEF were found in our study. The average of foramina to sagittal suture were 5.67 ? 2.73 mm on the right and 5.91 ? 2.37 mm on the left in male, while in female it was 5.28 ? 2.61 mm on the right and 5.48 ? 2.54 mm on the left. The shape was mostly circular with mean diameter of 1.27 ? 0.56 mm on the right, 1.23 ? 0.52 on the left and 1.11 ? 0.49 mm at the center in male. In female, the mean diameter of 1.19 ? 0.42 mm on the right, 1.12 ? 0.41 mm on the left and 1.60 ? 0.92 mm at the center. The ratio of distance from the external occipital protuberance (EOP)to PEF and to glabella in males on the right side is 0.342 cm. (3/8) and 0.349 cm. (3/8) on the left side. While the ratio of females is 0.367 cm. (3/8) and 0.388 cm. (3/8), respectively. Our finding obtained in this study scientists can be essentially benefited for anatomists, radiologists, neurosurgeons, and forensic to aware this anatomical structure.

RESUMEN: El foramen emisario parietal (FEP) es una importante estructura a través de la cual atraviesa la vena emisaria parietal. Los objetivos de este estudio fueron estudiar la morfometría del FEP y sus implicaciones clínicas. Se examinaron 800 huesos parietales (400 cráneos tailandeses pertenecientes a 200 hombres y 200 mujeres). Se encontró un total de 587 FEP en 344 cráneos, de los cuales 298 estaban presentes en el lado derecho y 256 en el lado izquierdo, siendo 155 FEP unilaterales, 189 bilaterales y 33 localizados en el centro. El promedio de la distancia de los FEP a la sutura sagital en los hombres fue de 5,67 ? 2,73 mm a la derecha y 5,91 ? 2,37 mm a la izquierda, mientras que en las mujeres fue de 5,28 ? 2,61 mm a la derecha y 5,48 ? 2,54 mm a la izquierda. La forma era mayoritariamente circular con un diámetro medio de 1,27 ? 0,56 mm en el lado derecho, 1,23 ? 0,52 en el lado izquierdo y 1,11 ? 0,49 mm en el centro en los cráneos de los hombres. En las mujeres, el diámetro medio del FEP en el lado derecho fue de 1,19 ? 0,42 mm, en el lado izquierdo 1,12 ? 0,41 mm 1,60 ? 0,92 mm en el centro. La relación de la distancia desde la protuberan- cia occipital externa al FEP y a la glabela en el lado derecho en los hombres fue de 0,342 cm (3/8) y en el lado izquierdo 0,349 cm (3/8). Mientras en las mujeres fue de 0,367 cm (3/8) y 0,388 cm (3/8), respectivamente. Nuestros hallazgos obtenidos en este estudio puede ser útil para que los anatomistas, radiólogos, neurocirujanos y científicos forenses conozcan esta estructura anatómica.
