Histopathological and biomarker complete response after neoadjuvant chemotherapy of advanced stage yolk sac tumor of the ovary: A case report and literature review

INTRODUCTION

Yolk sac tumor is the second most common germ cell ovarian carcinoma. Neoadjuvant chemotherapy (NACT) is proposed as an alternative option for patients with advanced disease who are not eligible for primary debulking. We presented a case with a systematic review of advanced yolk sac tumors of the ovary with poor performance who gain benefit from NACT.

CASE PRESENTATION

A 24-year-old female underwent NACT followed by surgery after being diagnosed with an advanced yolk sac tumor. A literature search was done based on the clinical question using the Patient/Problem, Intervention, Comparison, and Outcome (PICO) approach. Pubmed and Google Scholar were used to search the literature.

DISCUSSION

Out of 111 manuscripts found, 2 articles were retrieved for detailed evaluation. The patient showed a complete response in tumor size, histopathology, and tumor markers after the NACT procedure followed by surgery.

CONCLUSIONS

NACT is a suitable option for advanced yolk sac tumors of the ovary.

The Role of Stromal Tumour Infiltrating Lymphocytes (sTIL) Intensity and Programmed Death Ligand 1 () Expression in Breast Cancer Response to Neoadjuvant Therapy in Cipto Mangunkusumo Hospital (CMH), Indonesia

BACKGROUND

Pathological responses to neoadjuvant therapy were still relatively poor, especially in CMH. Studies had been done to search for predictors of response such as sTIL intensity and  expression, which is known to block sTIL action in killing cancer cells. This research assessed sTIL intensity and  expression as predictors of response to neoadjuvant therapy in breast cancer. The preliminary data might be used to better tailored breast cancer patient therapy, considering the availability of anti-PD-1/ PD- L1 immunotherapy nowadays.

OBJECTIVE

To assess TIL intensity,  expressions, and their roles as pathological predictors of breast cancer response to neoadjuvant therapy in Cipto Mangunkusumo Hospital (CMH).

METHOD

This was an observational analytic retrospective cohort study on breast cancer patients undergoing biopsy/review of biopsy specimens, receiving neoadjuvant therapy and mastectomy in CMH from January 2014 to December 2021. Sixty cases fulfilled the inclusion and exclusion criteria. Total sampling was done.   expression (immunohistochemistry, clone 22C3) and sTIL intensity (histopathology) was examined in the biopsy specimen. Linear regression analysis was done to determine the independent predictors of neoadjuvant therapy response (evaluated in the mastectomy specimen with residual cancer burden/ RCB score).

RESULTS

There were 60 female patients, median age 46 years old. 91,7% had invasive carcinoma of no special type. Median sTIL intensity was 10% (1%-70%). 58,3% patients had low sTIL intensity (≤10%). 28,3% patients had positive  expression (CPS ≥1). Only 8,3% patients had pCR, while 90% patients had RCB class II-III. Every 1% increase in sTIL intensity, no lymphovascular invasion, and taxane chemotherapy were predicted to lower RCB score by 0,058, 0,781, dan 0,594, respectively.  expression associated with pCR-RCB class I (p=0,048), but CPS score was not a predictor of RCB score in linear regression analysis.

CONSLUSION

sTIL intensity was an independent predictor of breast cancer response to neoadjuvant therapy in RSCM.  expression associated with pCR-RCB class I, but CPS score was not a predictor of RCB score.

High ALDH-1 Expression Predicts Non-Complete Response of Radiotherapy in Stage III Squamous Cell Cervical Carcinoma Patients

BACKGROUND

ALDH1 is a cervical cancer stem cell marker that has radioresistance profile. Recurrence and metastasis following radiotherapy are still being problems of most patients. This study aimed to determine the correlation between ALDH1 and radiotherapy response in stage III squamous cell cervical carcinoma (SCCC) of the cervix.

METHODS

A total 58 of 360 patients of stage III SCCC who received external beem radiation and brachytherapy (2016-2021) at Cipto Mangunkusumo Hospital met the eligibility criteria of this study. Pre- and post-irradiation MRI examinations and ALDH expression with immunohistochemistry (Santa Cruz®) were performed on formalin-fixed paraffin-embedded of pre-treatment cervical tissue biopsy taken from RSCM pathological anatomy laboratory. Patients were divided into two groups, complete responders vs non-complete responders. ALDH-1 scores were compared between two groups to assess ALDH-1 expression. The statistical analyses were carried out by SPSS 24.

RESULTS

The optimal ALDH-1 score cut-off point on the radiation response was 166.05 pg/mL which was obtained from the analysis of the ROC curve. The AUC value was 0.682 with sensitivity and specificity, 63,6% and 64%, respectively. ALDH score ≥166.05 increased the risk by 3.127 times for not achieving complete response (adj OR 3.127, 95% CI 1.034 - 9.456, p = 0.043). Pre-radiation tumor size (p = 0.593), degree of differentiation (p = 0.161), renal abnormalities (p = 0.114), and keratinization (p = 0.477) were not associated with radiation response.

CONCLUSIONS

High ALDH expression was associated with non-complete radiation response in stage III squamous cell cervical carcinoma.

Stromal Tumor Infiltrating Lymphocytes (sTIL) as an Independent Predictor of Pathologic Response to Neadjuvant Chemotherapy in Breast Cancer in Indonesia: A Hospital-based Study

OBJECTIVE

We aim to describe the sTIL profiles of Indonesian breast cancer patient and its role in predicting neoadjuvant chemotherapy response.

METHOD

This retrospective cohort study used secondary data from the archive of Anatomic Pathology Department FMUI/CMH. We did total sampling of 62 cases of locally advanced breast cancer cases that were biopsied, had neoadjuvant chemotherapy, and operated on from 2015 to 2020. We collected the clinicopathological data of each sample, measured the sTIL intensity in the biopsy specimen and evaluated the chemotherapy response from the mastectomy specimen using residual cancer burden (RCB) scoring method. Multivariate linear regression determined the independent predictors of RCB score.

RESULT

There were 62 female patients, 45.2% were Luminal-HER2-, 43.5% were HER2+, and 11.3% were triple negative (TN). Most sTIL intensity (59.7%) were low (median 10%; 1%-60%). Moderate-high sTIL intensity was associated with HER2+ type, while low sTIL was with luminal-HER2- (p=0.038). Only 8.1% patients achieved pCR. Statistically different median sTIL intensity in minimal, moderate, and extensive burden group were 28%, 20%, and 8%, respectively (p=0.002). sTIL was an independent predictor for better response (lower RCB score), which were 0.07 (95% CI 0.04-0.09) lower for every 1% increase in sTIL intensity.

CONCLUSION

sTIL intensity was mostly low in Indonesian breast cancer patient. However, it can predict neoadjuvant chemotherapy response, with 0.07 lower RCB score for every 1% increase of sTIL intensity.

Rare case of pelvic schwannoma mimicking intra-ligamenter uterine fibroid: A case report

INTRODUCTION AND IMPORTANCE

Schwannomas are benign tumors originating from Schwann cells of nerve fibers. Pelvic schwannomas are extremely rare. Here, we present a case of a 48-year-old woman with a pelvic schwannoma imitating degenerating cystic leiomyoma.

CASE PRESENTATION

A 48-year-old woman presented with brown-yellowish bloody vaginal discharge, fever, abdominal enlargement, and pain. Abdominal ultrasound showed a homogeneous solid mass with a clear border separated from the uterus and left ovary. Computed tomography (CT) scan revealed a multilocular cystic mass with thick septa and solid enhancing component. Histopathological examination showed a mesenchymal tumor composed of cells with fine chromatin. The nuclei were oval or round, and some cells exhibited spindle and cigar-shaped nuclei. Tumor cells had an abundant amount of eosinophilic cytoplasm. Immunohistochemical examination demonstrated positive expression for S100 as specific staining for schwannomas. Mitosis was not found, and hyalinized blood vessels were observed.

CLINICAL DISCUSSION

Compression by the tumor into the surrounding organs, such as the bladder and intestines, could cause difficulty with defecation and urination in patients. The absence of specific signs and symptoms can lead to a misdiagnosis of pelvic schwannoma. Surgery is the treatment of choice. It is difficult to establish a definitive diagnosis before surgery. Laparotomy approach was taken and a histopathological examination was completed to confirm the diagnosis.

CONCLUSION

Unspecified pelvic pain with abdominal mass may suggest a rare tumor such as schwannoma. Transvaginal ultrasonography is incapable of reliably distinguishing between schwannoma and other tumors.

Could combination of radical hysterectomy and radiation effective in the treatment of primary cervical signet ring cell carcinoma?: A rare case report

Introduction

Primary signet-ring cell carcinoma (PSRCC) of the uterine cervix mostly occurs due to the metastasis from the primary organ, such as the gastrointestinal tract or breast. This case describes the cervical PSRCC and its management as a rare case.

Presentation of case

The 39-year-old female came to undergo cancer screening. Visual Inspection with Acetic Acid (VIA) examination result was negative with the feature of severe cervicitis, and then the patient was given Trichloroacetic Acid (TCA) procedure. Three weeks after TCA's procedure, speculum examination found morphological features of cervix malignancy. Cervical biopsy examination showed mucinous adenocarcinoma, signet ring cell variant, with lymphovascular invasion. Endometrial microcurettage specimen do not contain tumor mass.

Discussion

The risk factor for cervical cancer in this patient was early sexual intercourse. We suggested stage IB2 cervical cancer because the tumor size was 2 cm until 4 cm, there was no spreading to nearby lymph nodes nor distant sites. Then patient had performed a radical hysterectomy procedure with ovary transposition and a series of radiation therapy. The patient was in good condition and no metastases were found in the imaging study.

Conclusion

The treatment of PSRCC of the uterine cervix is challenging. It was established from intraoperative findings, histopathology, and immunohistochemistry examination. The radical hysterectomy adjunct to radiation was effective in the treatment of the PSRCC of the uterine cervix.

•

Primary Signet Ring Cell Carcinoma (PSRCC) of the uterine cervix is a rare case, where in general, Signet Ring Cell Carcinoma (SRCC) as a subtype of mucinous adenocarcinoma and it is originated from gastrointestinal tract malignancy

•

PSRCC of uterine cervix was established from intraoperative finding and pathology examination

•

Combination of radical hysterectomy and radiation is effective in the treatment of PSRCC of uterine cervix

Hysteroscopy Role for Female Genital Tuberculosis

Female genital tuberculosis affects the quality of women's lives. One of the symptoms is amenorrhea. In our country, it is still underdiagnosed due to limited resources. Hysteroscopy is known as one of the diagnostic tools for this condition. We performed hysteroscopy and endometrial biopsy in four cases. Hysteroscopy findings show various signs. Histopathological examination showed typical features of tuberculosis in some cases. We also learned that hysteroscopy could evaluate the condition of the endometrium when ongoing and after treatment is accomplished. It is useful for further explanation to the client. Hysteroscopy can be utilized as a diagnostic tool for endometrial sampling, evaluate intracavity condition after treatment, and prognostic tool for future reproductive function.

Role of Ambulatory Laparoscopy in Diagnosis of Ascites with Unknown Etiology

Background: Ascites could be caused by many underlying diseases, mainly portal hypertension, malignancy, and heart failure. Other etiologies include tuberculosis and pancreatitis. Difficulties in confirming the cause of ascites have been seen in many clinical settings. Ambulatory laparoscopy is one of powerful tools to rule out many etiologies of ascites despite being invasive in its nature. This case report would like to show one case of peritoneal TB presenting with ascites. Patient has undergone many laboratory workups in search of ascites origin. Literature study is done to look for evidence about timing and role of laparoscopy in ascites work-up. Case illustration: A-26-year-old P2 woman came to hospital with a history of vaginal delivery 22 days before admission presenting with massive ascites. No obstetric complication was found. Transvaginal ultrasound revealed normal postpartum uterus and ovaries, surrounded with ascites. Both the liver and kidneys were found normal on ultrasound. Abdominal CT scan with contrast showed massive ascites with thickened omentum. ADA was 36 IU/L. We decided to perform diagnostic laparoscopy and biopsy for histopathology. We found massive yellowish ascites and hyperaemic tubal enlargement with thickening of the peritoneum. Pathology examination proved the appearance of chronic salpingitis and granulomatous peritonitis consistent with tuberculosis peritonitis. Conclusion: Laparoscopy as a minimal invasive tool can diagnose ascites with unknown etiology patients after failure to prove diagnosis from clinical laboratory and radiological examination. It is one best alternative to diagnose peritoneal TB presenting with ascites with its superiority in visualizing abdominal cavity and obtaining specimens for histology with lower risk of morbidity.

Rare case of huge vulvar angiomyofibroblastoma in a young female

•

Huge angiomyofibroblastoma of the Vulva.

•

Differential diagnosis between vulvar angiomyofibroblastoma and vulvar aggressive angiomyxoma.

•

Comprehensive approach diagnosing and therapy of vulvar angiomyofibroblastoma.

Mesenchymal tumours of the vulva are rare and consist of two types, difficult to distinguish but with different prognoses. Angiomyofibroblastoma (AMFB) is a benign tumour, whereas Aggressive Angiomyxoma (AA) is an infiltrating tumour. We describe a 22-year-old nulliparous patient with a vulvar mass sized 19 cm in diameter. After preoperative assessment by ultrasound, chest X-ray, and MRI, wide excision on the tumour was done and diagnosed as AMFB. Differentiation from AA is being discussed.

Ovarian steroid cell tumour (NOS) causing Cushing's syndrome in an extremely young girl: A case report

Steroid cell tumours are rare type of sex cord-stromal tumour of the ovary, with the average age at diagnosis during the fourth decade of life. A 2-year-old girl presented with virilisation, precocious pseudopuberty and Cushing syndrome. Her morning cortisol level was elevated and there was left lower abdominal mass found in radiological examination. An explorative laparotomy followed by a left salpingo-oophorectomy was performed. Histopathological examination revealed an encapsulated solid yellow-tan tumour composed of polygonal cells arranged in nests/lobes, containing numerous vascular channels, with abundant, clear-to-granular eosinophilic cytoplasm, severe nuclear pleomorphism and no Reinke crystals present consistent with an ovarian steroid cell tumour (NOS). The tumours cells were diffusely positive with calretinin, weak focal positive for inhibin, melan-A, pankeratin, chromogranin and negative for AFP, HMB-45 and androgen receptors. Following the tumour removal, blood pressure regressed to normal. The patient was discharged and advised for outpatient care.

Primary squamous cell carcinoma of the endometrium: A rare case report

Primary endometrial squamous cell carcinomas (PESCC) occur sporadically. It is defined as a primary carcinoma of the endometrium composed of squamous cells of varying degrees of differentiation. A 57-year-old female patient was referred to the gynaecological clinic of Faculty of Medicine, Universitas Indonesia, Dr Cipto Mangunkusumo National Referral Hospital because of abdominal enlargement with pain. Total hysterectomy and bilateral salpingectomy were performed. Histopathological examination confirmed a moderately differentiated squamous cell carcinoma, with lymph-vascular invasion. Two weeks after the operation, the patient complained of a mass on her left supraclavicular area. Fine needle aspiration biopsy revealed squamous cell carcinoma metastatic in nature. The recommended treatment was paclitaxel (175mg/m²) and carboplatin (AUC- 6), combined with pelvic radiotherapy.

Rapidly recurring ovarian fibrosarcoma after optimal debulking surgery in a 46-year-old woman

Ovarian fibrosarcoma is an extremely rare tumour with no universally accepted guidelines for treatment. We present a 46-year-old nulliparous woman with ovarian fibrosarcoma who mainly presented with a painful abdominal enlargement. Optimal debulking surgery was performed, and a specimen of the tumour was examined. A frozen section examined during surgery revealed spindle cell morphology, raising the suspicion of ovarian fibrosarcoma, which was later confirmed by immunohistochemistry staining. Our patient refused to undergo chemotherapy and died 3 months after surgery due to tumour recurrence. Although no clear consensus exists for administering chemotherapy for fibrosarcoma, some published case reports have shown a lower chance of recurrence and better prognosis in patients who undergo chemotherapy compared with our patient.

The Dynamics of Cullin-1 Expression in Preeclamptic Placenta and its Association with Pregnancy Termination Time

BACKGROUND: Preeclampsia is a systemic syndrome occurring in 3–5% of pregnancies, caused by disorders of cellular factors resulting in the disruption of trophoblast differentiation and invasion which is important for the placental development and maintaining pregnancy. Cullin-1 is a protein that plays a role in the process of maintaining pregnancy, development, and trophoblast invasion in the placenta. Until now, there have been no studies linking the expression of cullin-1 in preeclamptic patients with the timing of pregnancy termination. AIM: This study analyzed cullin-1 expression in preeclamptic patients and their relationship to the timing of pregnancy termination was carried out. METHODS: Placental samples were taken from preeclampsia patients consisting of three gestational age groups, then immunohistochemical staining was performed to see the dynamics of expression and distribution in each age group of pregnancy and to find out their relationship with the timing of pregnancy termination. RESULTS: Cullin-1 was expressed in syncytiotrophoblasts and cytotrophoblasts. The lowest cullin-1 level was obtained in the very preterm age group, and the highest was found in the moderate preterm gestational age group. There was a significant difference between cullin-1 optical density (OD) expression and termination time of pregnancy, and there was a significant difference (OD) in cullin-1 preeclamptic patients with very preterm gestational age with moderate preterm gestational age. CONCLUSION: Cullin-1 was expressed both in syncytiotrophoblasts and cytotrophoblasts and was associated with the timing of pregnancy termination.
