Pap smears, human papillomavirus(HPV) screening, tumor marker status, biopsy analysis, and relevant imaging examinations were conducted for the confirmation of primary diagnosis and recurrence. Patients underwent surgery, chemotherapy, or radiotherapy, and survival were the main endpoint.Results The 4 patients were diagnosed with IB1, IB1, IIA, or IIIB disease. Two patients(2/4) presented with recurrence within 18 months after primary therapy. Compared with chemotherapy alone(progressionfree survival(PFS): 11 months), radiotherapy combined with adjuvant chemotherapy showed favorable PFS rates(PFS: 20, 36, 13 months in 3 cases), although valid statistical analysis was not feasible because of the small sample size. The 5-year survival rate was 0%, and the 3-year survival rate was 75%. Our data, in agreement with the literature evidence, showed that the number of moderate-risk and high-risk factors in patients diagnosed with PSCC at an early stage was higher than that in patients diagnosed with common adenocarcinoma/squamous carcinoma of the uterine cervix.Conclusion PSCC has a poor clinical prognosis, and compared with chemotherapy alone, radiotherapy combined with adjuvant chemotherapy may lead to improved PFS.展开更多

The predicament is further worsened by poor uptake of cytological screening programs, which are either not available or where available are underutilized due ?to lack of widespread awareness and the cost as ???an average Nigerian earns less than a dollar per day. In addition to the above constrains, majority of these patients also presents late to the hospital for intervention. Objective: To emphasize the significance of punch biopsy and clinical staging of advanced carcinoma of the cervix and see how we can shift from our traditional, Examination under Anesthesia (EUA) to Clinical staging and punch biopsy for advanced carcinoma of the cervix. Methodology: Review of existing literature and experience from our own center. Results: The punch biopsy has 88.8% positive predictive value in making a diagnosis of cancer of the cervix. Late presentation was as high as 81.7 percent for carcinoma of the cervix in our centre. The patients present late for care;majority actually presents in stages III & IV when little or nothing can be done for them. Conclusion: In view of these predicaments that face a gynecological oncologist practicing in low resources settings like ours, there is a need to consider the role of punch biopsy, clinical staging and radio-logical assessment for making a diagnosis, especially among those women who cannot afford EUA or are having renal complication that makes EUA unachievable.展开更多

At our centre two Varian made Fletcher-style applicator sets, namely defined (fixed) geometry and flexible geometry, are used for ICRT. In the present work, the two types of applicators were compared dosimetrically as per the recommendations of the International Commission on Radiation Units and Measurements (ICRU-38) while delivering high dose rate brachytherapy. Twenty four patients who underwent ICRT were considered for this study. Radiographic method was used for treatment planning on Abacus planning system. ICRU-38 recommended parameters were estimated and compared. Flexible geometry applicator showed 8.8% and 16% higher bladder and rectum point doses as compared to the fixed geometry one but the difference was statistically not significant. The thickness of the pear-shaped isodose volume was larger for the flexible geometry implant also indicating towards higher doses to OARs. The higher bladder and rectum point doses in the case of flexible applicator will need to be validated by a larger data set.展开更多

Very rarely, it may affect the uterine cervix. We report here a case of a woman with postmenopausal bleeding for 7 months, who on physical examination presented with a vegetative and friable tumor lesion in the uterine cervix, measuring about 5 cm in diameter. The abdominal and pelvic computed tomography scans showed a hypodense and heterogeneous mass in the cervix and uterine isthmus. Histopathological examination and immunohistochemical assays confirmed the diagnosis of ACC. The different pathological aspects, therapeutic options and prognostic factors of ACC are discussed.展开更多

Materials and Methods: One hundred and two cases of carcinoma cervix were included in the study. All patients were treated with a curative intent with radical dose of radiation as per the department protocol. All patients were treated with both EBRT plus Brachytherapy with Inj. Cisplatin 40 mg/m2 weekly. Patients were divided into 2 groups based on activity i.e. group A (10-6Ci) and group B (5-2Ci). After brachytherapy, point doses were analysed based on ICRU 38 recommendations. During follow up, morbidities were evaluated using RTOG grading system. Results: There was no difference in local control and distant metastasis in both groups after six months of follow up. Late Complications were comparable in both groups irrespective of source strength. Bladder complications were minimal with no significant difference in both study groups. Further Patients were divided into four groups i.e. BED of ICRU rectal point (3 and ≥100 Gy3) and source strength (10-6Ci and 5-2Ci), when BED was >100 Gy3 resulted in higher late rectal complication rate (P 3. Conclusion: This study suggests that change in source activity did not make a difference in local control, late rectal and bladder morbidities at 6 months of follow up. Longer follow up is required to assess long term results and morbidities.展开更多

The five-year tumor free acturial survival for the patients with stage IB either with irradiation alone (RT) or combined with surgery (RS) was approximately 87%. For stage Ⅱ the tumor free actuarial five-year survival 79% with patients of RS, and 76% with RT. In the 113 patients treated with RS there were 18 (16%). In the 139 patients treated by RT there were 18 (13%) recurrences of pelvic, 4 local recurrences, 11 combined with parametrial, and free parametrial recurrences. There was no significant difference in the survival and recurrence rate of the patients treated with either method. Major complications were comparable in both groups (RT approximately 25% and RS approximately 10%), but 2/3 of those complications recovered without sequelae. The most frequent minor complication in the patients treated with RT was rectosigmoiditis.展开更多

Methods： Immunohistochemisty technique was used to detect the expression of Fas and FasL in 47 cases of cervical carcinoma, 16 cases of cervical interaepithelial neoplasia, 10 cases of chronic cervicitis and 10 cases of normal cervix. TUNEL technique was used to observe the apoptic cells in 47 cases of cervical carcinoma. Retrospective study was carried out to find the relationship between the expression of Fas and FasL and cell apoptosis, clinical stage, pathological classification, lymph node metastasis, prognosis and age. Results： The expression of Fas and FasL was significantly different in different cervix （P 〈 0.01）, and also related to the degree of differentiation, lymph node metastasis and prognosis （P 〈 0.05）. But had no relation with clinical stage or age （P 〉 0.05） ; Cervix carcinoma cells apoptosis in different pathological classification appeared negative relation （Rs=-0.35, P 〈 0.05 ）. Cervix carcinoma cell apoptosis was significantly higher in Fas-positive and FasL- positive than that in Fas-negative and FasL-negative （P 〈 0.05）. By retrospective investigation, Fas-negative and FasL-positive were related to poor prognoses of the patients with cervical carcinoma （P 〈 0.05 ）. Conclusion： The development of apoptosis in cervix carcinoma has a promoting regulation function in Fas and FasL expression. Gene treatment can alter apoptosis abnormality, thus induce apoptosis in cancerous cell expressing Fas and FasL. Fas or FasL may be taken as a marker in the prognostic character- ization.展开更多

Several researches done in the last decade have evaluated the role of this technique in assessing carcinoma of the cervix. However there is a significant paucity of literature linked to pre-malignant lesions of the cervix and its diagnosis based on transvaginal colour doppler and its pulstality index (PI). In this paper we present a case control study conducted to assess the validity of transvaginal colour doppler scan and PI in diagnosing malignant and pre-malignant lesions of the cervix. Methodology: A case control study with a total sample of 57 women was conducted at the Nawaloka Hospital for duration of two years. 19 cases of recently diagnosed patients with cervical carcinoma, using cytobrush and colposcopy guided biopsy, evaluated by a consultant histopathologist, were recruited. Staging was done according to FIGO classification. 40 age-matched patients with histologically confirmed normal cervix were selected as controls and 2 were excluded from the study due to the presence of cervical infection. All cases and controls were subjected to transvaginal colour doppler sonography using a 5 MHz 3D probe using GEvolusion6 US machine. The machine was also set for high pass filter at 100 Hz to eliminate low frequency signals occurring from vessel-wall motion. Cervical colour doppler ultrasonography pattern was captured in each case of malignancy, pre-malignancy and controls, and pulstality index (PI) was assessed by the lead gynecologist accredited with ISUOG standards. The highest PI was assessed and recorded in the descending branch of the uterine artery. Results: Women’s mean age was 55.5 years (range 35 - 78). According to clinical staging, there were 4 females with carcinoma in situ, 4 Females with Stage I a, 3 with Stage I b, 4 with Stage II a and 4 with Stage III a. Histologic examination revealed 13 women with squamous cell carcinoma, 2 women with adenocarcinoma and 4 with carcinoma in situ (CIN III) of the cervix. Mean PI value for the cases were 1.94 (range 1.2 - 3.1) and the mean PI value for the controls were 0.805 (range 0.3 - 1.5). Neovascularization was markedly seen in the patients with invasive cervical carcinoma with a PI ranging between 1.99 and 3.10. Chi square test results showed a very high statistically significant difference of PI values between cases and controls (p value < 0.0001). An ROC analysis revealed the optimal cut-off value of PI at 1.475 with a sensitivity of 89.5% and a specificity of 93.5%. Conclusion: Transvaginal doppler ultrasonography and PI of the descending cervical branch of the uterine artery and its branch vasculature allow a non-invasive assessment of tumor vascularization in cervical carcinoma and pre-malignancy. PI with a cut off value of 1.475, can be reliably used to detect and screen pre-malignancies and malignancies at a relatively early stage with a sensitivity of 89.5% and a specificity of 93.5% enabling further definitive evaluation, in a routine gynecology trans vaginal ultrasound assessment.展开更多

The appropriate clinical management of this condition, particularly of the pain related to malignant psoas syndrome, is still evolving and the diagnostic features on conventional morphological imaging modalities are often non specific, with the differential diagnosis lying between sarcoma, hematoma, and abscess. In this report, a comparison of various morphofunctional imaging modalities was made. Fluorodeoxyglucosepositron emission tomography(FDG-PET)/computed tomography(CT) was the first to suspect disease involvement of the psoas muscle, demonstrating intense FDG uptake(compared with the contralateral muscle), while ultrasound showed heterogeneous echotexture, and magnetic resonance imaging(MRI) showed subtle altered signal intensity in the right psoas muscle. Both anatomical imaging modalities and non contrast CT of the PET-CT examination demonstrated a bulky psoas muscle, without any focal abnormality. On diffusionweighted imaging of MRI(DWI-MRI), restricted diffusion of the involved muscle was an important observation. The psoas muscle metastatic involvement was proven histopathologically. Thus, enhanced glucose metabolism and restricted diffusion in the newer noninvasive molecular imaging modalities(e.g., PET/CT and DWI-MRI) could serve as valuable adjunctive parameters in diagnosing this entity in the absence of a focal abnormality in the anatomical modalities. In the treatment response monitoring scenario, FDG-PET/CT demonstrated near complete resolution following administration of 3 cycles of systemic chemotherapy and local external radiotherapy.展开更多

In this report, a comparison of various morphofunctional imaging modalities was made. Fluorodeoxyglucosepositron emission tomography(FDG-PET)/computed tomography(CT) was the first to suspect disease involvement of the psoas muscle, demonstrating intense FDG uptake(compared with the contralateral muscle), while ultrasound showed heterogeneous echotexture, and magnetic resonance imaging(MRI) showed subtle altered signal intensity in the right psoas muscle. Both anatomical imaging modalities and non contrast CT of the PET-CT examination demonstrated a bulky psoas muscle, without any focal abnormality. On diffusionweighted imaging of MRI(DWI-MRI), restricted diffusion of the involved muscle was an important observation. The psoas muscle metastatic involvement was proven histopathologically. Thus, enhanced glucose metabolism and restricted diffusion in the newer noninvasive molecular imaging modalities(e.g., PET/CT and DWI-MRI) could serve as valuable adjunctive parameters in diagnosing this entity in the absence of a focal abnormality in the anatomical modalities. In the treatment response monitoring scenario, FDG-PET/CT demonstrated near complete resolution following administration of 3 cycles of systemic chemotherapy and local external radiotherapy.
