A 61-year-old woman presented with a 2-month history of non-painful left eye proptosis. Imaging studies showed a superotemporal mass in the left orbit with intracranial extension. Surgical excision of the orbitocranial mass was performed and histopathologic examination revealed metastatic papillary thyroid carcinoma. She subsequently underwent total thyroidectomy. Orbital metastasis from thyroid carcinoma is rare and can be the initial manifestation of occult disease in 63% of cases.

BACKGROUND AND OBJECTIVE

Meningiomas represent the most prevalent benign intracranial tumors, comprising 13- 26% of primary intracranial neoplasms. These tumors derive their blood supply from both extracranial and intracranial circulation. Over recent decades, pre-operative embolization (POE) has emerged as a potential adjunctive therapy to surgery, aiming to reduce tumor vascularity. Our study seeks to explore the potential correlation between the extent of devascularization following POE of meningiomas and intraoperative blood loss.

This cross-sectional study involved nine meningioma patients at a tertiary hospital, involving chart review of patients across four years. These patients were referred for POE due to angiographic evidence of a hypervascular mass between January 2018 and January 2022. We collected demographic data, tumor characteristics (including location, size, and vascular supply), and intraoperative variables such as total operative time and blood loss. Statistical analyses aimed to uncover correlations between vascularization degree and various factors.

Our population consists predominantly of females (53.68%), with a mean age of 45.85 ± 13.65 years. Only one mortality was recorded (7.7%). Pre-operative embolization achieved devascularization in the majority (69.2%) of cases, with approximately two-thirds (66.7%) experiencing complete devascularization. Mean total operative time stood at 336.11 ± 301.88 minutes, with a mean post-operative blood loss of 985.56 ± 1013.72 milliliters. Additionally, for those with recorded recovery times, the mean recovery time was 14.32 ± 13.51 hours.

Mortality rates showed no association with sex, devascularization status, or number of feeding vessel zones. Furthermore, the extent of devascularization did not correlate with age, sex, number of feeding vessel zones, postoperative blood loss, total operative time, or recovery time (p >0.05).

In summary, this study represents a significant endeavor to elucidate factors influencing meningioma outcomes following pre-operative embolization. Despite limitations regarding patient numbers, our study offers valuable insights into operative parameters and embolization considerations for future analyses in our tertiary center.

BACKGROUND

Cervical cancer remains to be the second leading cancer and cause of cancer-related deaths among Filipino women despite the use of the Papanicolaou screening. Latest research has shown that the human papillomavirus (HPV) is a necessary cause of cervical cancer. With major morbidity and high mortality rates associated with HPV infection and cervical cancer, several modes of primary and secondary forms of prevention have to be implemented. Among the primary modes of prevention is the administration of the preventive vaccine, which has consistently shown to decrease substantially HPV disease and cervical cancer rates in developed countries. In our country, before a successful vaccination, program is implemented, several sociocultural issues have to be addressed. Knowledge, attitude, and motivational factors are vital in determining acceptance of the vaccine. One relevant setting is exploring the willingness of mothers to get their female children vaccinated even before they become sexually active.

The aim of the study was to determine the association of the knowledge, attitude, and motivational factors of mothers on their willingness for their female children aged 9–13 years to undergo HPV vaccination at a tertiary government hospital.

This was a cross-sectional study that was carried out at a government institution.

The population consisted of 352 mothers with female children aged 9–13 years consulting the outpatient clinics at the department of obstetrics and gynecology at a tertiary government hospital.

A pretested and validated survey was given to 352 respondents. They were asked to answer a self-administered questionnaire that included sociodemographic, reproductive, sexual history variables, knowledge, and attitude, and motivational factors toward the disease and the associated vaccine.

Using the survey proportion estimation methods, the prevalence of women who were willing to enroll their daughters for HPV vaccination was 97.18% (n = 42, 95% confidence interval [CI]: 94.91 to 98.46%). It can be noted that only a third of the sample had high knowledge on the vaccine and its use 34.93% (n = 124, 95% CI: 30.25 to 39.92%). More women who reached college level (χ2: 5.67) and also those whose youngest child was between 11 and 13 years old (χ2: 8.82)-had higher knowledge scores than otherwise. Those who have an annual income of greater than or equal to P 60,000 (χ2: 16.55) and are non-Catholic (χ2: 18.77) – also appeared to have higher knowledge ratings on the questionnaire. Women who never to a few times a year attend church-related activities had higher knowledge scores compared to women who were more frequent goers (χ2: 16.33). For the attitude toward the vaccine, more mothers believed that getting the vaccine would not have an effect on a girl’s sexual activity and most agreed that they would not be viewed as bad parents. Most women also did not believe that religion would affect their willingness to vaccinate their children. There was an association in the degree of agreement between negative and positive attitudes from the Chi-square test performed (χ2: 7.44, P: 0.01). There were more agreeing responses from factors determining positive attitude and more disagreeing responses in the factors determining negative attitude. With regard to motivational factors, more women agreed that the cost was prohibitive and that they were more willing if only two doses would be required for their daughters. They were also not concerned about what other parents may think about getting the vaccine. Most answered that they were willing to follow their doctors’ recommendations and they have trust in vaccine manufacturers. Most women were also concerned that their daughters may get cervical cancer in the future. There was no difference in the proportion of agreeing responses between positive and negative motivating factors among the study participants (Z: 0.30, P: 0.79). This suggested that these factors could be important predictors of willingness to use vaccination on their children. Based on the crude odds ratios from the logistic regression, the likelihood of being willing to administer HPV vaccine to their children was almost twice as the knowledge score and scores on the positive attitude items increased, and was found to be statistically significant. At the same time, the odds of willingness increased by more than twice as the score on the negative attitude items decreased, and was also significant. There was no noted association for the other predictors of the association.

The role of knowledge and attitudes on the negative perceptions on the vaccine were important predictors of the willingness of mothers to have their female children vaccinated against HPV infection.

INTRODUCTION

Papillary thyroid cancer (PTC) is generally considered to be an indolent disease with relatively good prognosis. However, some studies have shown that the Filipino population has a higher risk for disease recurrence compared to non-Filipino patients and hence early identification and management during the follow-up period would be beneficial, especially those in whom risk factors for recurrence were identified.

This study aims to identify determinants for disease recurrence of patients with papillary thyroid carcinoma (as defined by the American Thyroid Association (ATA) guidelines 2015) diagnosed from January 1, 2013-December 31, 2017, seen at the University of Santo Tomas Hospital (USTH) outpatient endocrine clinic and underwent total thyroidectomy with or without radioactive iodine ablation therapy.

Retrospective review of outpatient medical records of 82 patients with PTC who underwent total thyroidectomy with or without radioactive iodine (RAI) therapy and achieved excellent response (ER) to therapy was performed. Baseline clinical profile such as age at diagnosis, sex, family history of thyroid cancer, family history of goiter, histopathology result, serial thyroglobulin (Tg), anti-thyroglobulin (anti-Tg) levels, whole body scan reports, neck ultrasound reports and RAI doses were collected. Logistic regression analysis was used to identify determinants to the development of worsening response.

Of the 82 patients, 18 (21.9%) developed worsening response to therapy. Predictors of poor outcomes identified from previous studies such as age, sex, extent of disease, size and multifocality of tumors, ATA risk classification and initial dynamic risk assessment, RAI therapy, level of thyroid-stimulating hormone (TSH) suppression were analyzed. After logistic regression analysis, there was no significant association between variables and progression to worsening response that were previously identified in other studies.

Even though no significant association between investigated variables and worsening response were identified in this study, previous studies with larger populations that had exhibited positive association should be considered and hence current Philippine guidelines for the management of PTC must still be applied.

Familial Adenomatous Polyposis (FAP) is a multi-tumoral syndrome that includes neoplasms in the duodenum, brain, pancreas and thyroid. The Cribriform Morular Variant (CMV) is a rare form of Papillary Thyroid Cancer seen in patients with FAP. Presented here is a 32 year old female who initially presented with an anterior neck mass followed years later by a rectal mass. She was diagnosed with FAP and colorectal adenocarcinoma and underwent total proctocolectomy with end ileostomy. She subsequently underwent a total thyroidectomy which revealed CMV Papillary Thyroid Carcinoma (CMV-PTC). Since FAP can have diverse presentations, a high index of suspicion is needed in order to make an earlier diagnosis to reduce potential morbidity and mortality. Papillary thyroid carcinoma can predate colonic polyposis. Identifying CMV-PTC early on can serve as an opportunity diagnose FAP early.

BACKGROUND AND OBJECTIVE

The burden of treatment delay in breast cancer is high, especially among developing countries. Despite adversely affecting morbidity and mortality, treatment delay remains unexplored in the Philippines. This study aimed to determine treatment delays among breast cancer patients in a tertiary hospital during surgery, neoadjuvant chemotherapy, and adjuvant chemotherapy, and to identify predictors of delay.

A cross-sectional study was conducted among breast cancer patients seen between January 1, 2012 to December 31, 2018. The following outcomes were investigated: ≥90 days from initial diagnosis to surgery, ≥8 weeks from diagnosis to initiation of neoadjuvant chemotherapy, and >120 days from diagnosis to initiation of adjuvant chemotherapy. Summary statistics were reported as percent for categorical data and as mean for continuous data. The individual correlations were performed using Chi-square for qualitative data and t-test for quantitative data while predictors were determined through logistic regression.

A total of 324 patients were included in this study. The majority of the patients were less than 65 years old living in urban areas. More than half of the patients were overweight or obese, hypertensive, and diabetic. The following delays were observed: 61.1% (n = 198) with any type of delay, 23.8% (n = 53) with delay in surgery, 53.8% (n = 120) with delay in adjuvant chemotherapy, and 74.3% (n = 75) with delay in neoadjuvant chemotherapy. The patients noted to have any type of delay were more likely to be hypertensive (p = 0.046) and residing in urban areas (p = 0.041). There were no differences in the distribution of age, body mass index, and presence of co-morbid conditions such as hypertension, diabetes mellitus, coronary artery disease, and heart failure among those with any form of delay compared with no delay.

The present study shows the presence of treatment delay among breast cancer patients and may be used to enact policy changes to optimize breast cancer care delivery. Further studies may be done to identify other factors affecting these delays and policy changes are recommended to address these gaps in surgery and chemotherapy administration among breast cancer patients.

OBJECTIVES: This study aimed to evaluate the diagnostic accuracy of Cyclin D1 as an adjunct immunomarker in CD99 positive small round cell neoplasms with primary consideration of PNET/EWS. MATERIALS AND METHODS: Tissue from 2017 to 2023 with a histopathologic diagnosis of CD99 positive small round blue cell tumors with primary consideration of Primitive Neuroectodermal Tumor (PNET)/Ewing Sarcoma were retrieved and Cyclin D1 immunohistochemical staining done. Diagnostic accuracy of Cyclin D1 immunostaining was determined by calculating the sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: Cyclin D1 immunohistochemical staining was performed in 19 specimens available, of which 13 yielded a positive result. Of these, 8 had a final histopathologic diagnosis of CD99 positive small round blue cell tumor with primary consideration of PNET/Ewing Sarcoma, resulting in sensitivity of 61.54%, specificity of 100%, positive predictive value of 100% and negative predictive value of 50.0%. The overall accuracy is 72.2%. CONCLUSION Cyclin D1 can be used as an adjunct immunomarker to aid in the diagnosis of CD99 positive round cell tumor with primary consideration of PNET/Ewing Sarcoma specifically in resource limited settings where molecular testing is not readily available. Given the high specificity of Cyclin D1 in such cases, it can be used to rule out other small round blue cell tumors that can also stain positive for CD99 such as Rhabdomyosarcoma. However, interpretation must be done in conjunction with the results of other immunohistochemical stains in order to increase its diagnostic accuracy.

INTRODUCTION

Neurofibromatosis type 1 (NF1) is an autosomal dominantly inherited condition seen in one of 4000 live births, predisposing to peripheral and central neurofibromas. Spinal tumors are seen in 40% of cases with NF1 and only 2% will develop symptoms, and among those who develop symptoms where 33% showed intradural extramedullary location. Thoracic spinal dumbbell neurofibroma is even rarer, and cases that extend to obliterate the posterior mediastinum even more so, with the case presented being the largest in size documented to date.

A 34-year-old female presented since childhood clinical findings consistent with Neurofibromatosis Type I: generalized cafe-au-lait macules, axillary freckling, cutaneous neurofibromas, two iris Lisch nodules identified via slit lamp examination, and anterolateral bowing of the right tibia, and no known parental history of Neurofibromatosis Type I. Prior to admission, the patient presented with progressive loss of motor strength of the lower extremities, and progressive dyspnea. Work-up revealed a Thoracic Intradural Extramedullary Neurofibroma extending to the Right Posterior Mediastinum measuring 15.3 cm x 12.9 cm x 9.7 cm in the thoracic cavity compressing the right lung and bronchus. An extensive two stage surgery was contemplated involving an initial resection of the Intradural mass, with spine instrumentation for support, and subsequent resection of the mediastinal extension. However, complications from the compressing tumor: complete cord transection syndrome causing spinal autonomic dysfunction, lung and airway compromise causing prolonged intubation and difficulty in weaning from mechanical ventilatory support, extensive thrombus formation in the right jugular vein, and nosocomial infections all created compounding difficulties for the surgical technique and anesthetic plan.

Cornerstone management for dumbbell spinal neurofibromas involves their total removal. The best results are obtained in patients showing minimal neurological deficits during the preoperative period. However, little improvement may be expected from patients who develop complete transection syndrome during the postoperative period. Concurrent medical management to prepare the patients are equally important. The multi-subspecialty approach required in managing these cases entails a good balance between the disability before the surgery, anticipated outcomes, and quality of life of the patients.

OBJECTIVES

To determine the incidence of prostate cancer on follow up after an initial negative MRI- fusion biopsy of the prostate, and to determine the change in PSA and MRI results on follow-up.

MRI-fusion prostate biopsy registry from 2018 to 2022 was obtained then histopathology, MRI results, and PSA results were obtained. Repeat PSA and MRI results at extracted at 3 years. PSA mean, range, and change were then determined. MRI results were extracted to determine progression, regression, or persistence.

A total of 670 prostate biopsies were done in the study period, of which 70 were included. PSA on biopsy 9.93 (3.35 – 55.0) with corresponding PIRADS lesions 3, 4, and 5 (n=55, n=19, and n=6). No patient was subsequently diagnosed with prostate cancer on follow-up. PSA mean 7.03, 6.44, 5.27, and 6.07 at 3years interval from biopsy. Repeat prostate MRI showed persistence in 1 and regression in 6 patients.

After a negative MRI-fusion biopsy of the prostate no patient developed prostate cancer with a general decrease in trend in PSA and MRI on follow-up. These patients may have longer interval follow-up periods given the clinical scenario but would be best to test this method in prospective trials first.

Leukemoid reaction refers to reactive and excessive leukocytosis with a white blood cell count of more than 50,000 cells/mm3 in the absence of myeloproliferative neoplasm and has usually been described in response to inflammation, severe infection, malignancies, hemorrhage, acute hemolysis, or bone marrow stimulants. In contrast, urothelial cell carcinoma is rarely associated with leukemoid reaction, with few cases reported over the past few years. Here, we report a case of an invasive Urothelial carcinoma of a 63 year old patient presenting with terminal dysuria and excessively elevated and persisting leukocytosis accompanied by rapid tumor progression and deteriorating clinical status. For urothelial cell carcinoma patients exhibiting a leukemoid reaction, removal of the inciting tumor is the definitive treatment. Though placing of urethral catheter and resection of the bladder tumor alleviated the worsening renal status and terminal dysuria on the index patient, the patient still had multiple persistent febrile episodes throughout the course, accompanied by leukocytosis with predominant mature looking neutrophils, and a left shift. Extremely persistent leukocytosis appears to be associated with poor prognosis even after surgical resection and extensive medical management.
