Abstract
BACKGROUND AND OBJECTIVE Diffuse reflectance spectroscopy (DRS) offers a fast, non-invasive, and low-cost alternative for cervical cancer diagnosis. We aim to develop a method for screening precancerous lesions based on DRS. MATERIAL AND METHODS Characteristic parameters of cervical tissue were extracted from spectra, including optical characteristic parameters such as absorption and scattering coefficients, and some slope and area parameters of the spectrum. Data were randomly divided into training (60%) and test (40%) sets. Of the 210 included patients, 166 were healthy, 22 had erosion of the cervix, and 31 had cervical intraepithelial neoplasia (CIN). The support vector machine (SVM) algorithm was used to classify normal and abnormal cervical tissue based on 11 characteristic parameters. RESULTS The SVM with linear kernel function, applied on the training data, could distinguish tissue with lesions from healthy tissue with an accuracy of 1.00. When the classifiers were applied to the test set, erosion of cervix and CIN could be discriminated from healthy tissue with an accuracy of 0.95 (±0.03). CONCLUSIONS This research shows that the diagnostic algorithm can be valuable for non-invasive diagnosis of cervical cancer. This is a significant step toward the development of a tool for tissue assessment of cervical cancer.

Radical Hysterectomy After Neoadjuvant Chemotherapy for Locally Bulky-Size Cervical Cancer: A Retrospective Comparative Analysis between the Robotic and Abdominal Approaches. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16203833. [PMID: 31614465 PMCID: PMC6843229 DOI: 10.3390/ijerph16203833] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 09/25/2019] [Accepted: 10/09/2019] [Indexed: 12/18/2022]
Abstract
Radical hysterectomy (RH) is the standard treatment for early stage cervical cancer, but the surgical approach for locally bulky-size cervical cancer (LBS-CC) is still unclear. We retrospectively compared the outcomes of women with LBS-CC treated with neoadjuvant chemotherapy (NACT) and subsequent RH between the robotic (R-RH) and abdominal approaches (A-RH). Between 2012 and 2014, 39 women with LBS-CC FIGO (International Federation of Gynecology and Obstetrics) stage IB2–IIB were treated with NACT-R-RH (n = 18) or NACT-A-RH (n = 21). Surgical parameters and prognosis were compared. Patient characteristics were not significantly different between the groups, but the NACT-R-RH group had significantly more patients with FIGO stage IIB disease, received multi-agent-based NACT, and had a lower percentage of deep stromal invasion than the NACT-A-RH group. After NACT-R-RH, surgical parameters were better, but survival outcomes, such as disease-free survival (DFS) and overall survival (OS), were significantly worse. On multivariate analysis, FIGO stage IIB contributed to worse DFS (p = 0.003) and worse OS (p = 0.012) in the NACT-A-RH group. Women with LBS-CC treated with NACT-R-RH have better perioperative outcomes but poorer survival outcomes compared with those treated with NACT-A-RH. Thus, patients with FIGO stage IIB LBS-CC disease might not be suitable for surgery after multi-agent-based NACT.

Abstract
Aim This retrospective study sought to identify the selection criteria required for a non‐radical hysterectomy with minimal parametrectomy in patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB invasive cervical cancer. Methods Overall, 461 patients with FIGO stage IB cervical cancer who underwent a radical hysterectomy were reviewed clinicopathologically according to pathological tumor size (≤2 cm, >2 – ≤4 cm, and > 4 cm). Results The pathological parametrial involvement rate in the less than equal to 2 cm group (2%) was significantly lower than in greater than 2–less than equal to 4 cm (13%) or greater than 4 cm (29%) groups (both P < 0.001). The 5‐year overall survival rate was significantly higher in the less than equal to 2 cm group (97%, 95% confidence interval [CI] 94–99%) compared with greater than 2–less than equal to 4 cm (90%, 95% CI 94–86%) and greater than 4 cm (70%, 95% CI 79–60%) groups (both P < 0.001). Cox model analysis identified tumor size to be an independent prognostic factor for survival (95% CI 1.33–5.78) and recurrence (95% CI 1.31–5.66) compared to other pathological factors. However, a significant difference between the three groups was not found in rates of Grade 3 or 4 adverse events following radical hysterectomy (P = 0.19). Conclusions Tumor size is an independent prognostic factor for survival in patients with FIGO stage IB invasive cervical cancer. This retrospective study suggests that FIGO stage IB patients with a less than equal to 2 cm tumor size are optimal candidates for non‐radical hysterectomy with minimal parametrectomy, and without resulting bladder dysfunction.

Abstract
Introduction During the last 3 decades, the standard treatment for stage Ia2-Ib1 cervical cancer has been Piver-Rutledge class II or III radical hysterectomy. However, this surgery is associated with a high rate of urologic morbidity. Aim To determine the efficacy of class I radical hysterectomy compared with class III radical hysterectomy in terms of morbidity, overall survival, and patterns of relapse in patients with Ia2-Ib1 cervical cancer undergoing primary surgery. Material and methods A total of 101 patients with stage Ia2-Ib1 cervical cancer < 2 cm were randomized to class I and class III hysterectomy groups. Clinical, pathologic, and follow-up data were prospectively collected. Univariate analysis was carried out. Of the total patients, 45 were randomized to class I surgery and 56 to class III surgery. No significant differences were observed in terms of pathologic findings or adjuvant treatment (p > 0.05). The morbidity rates were higher after class III surgery. Results The difference in recurrence rate between the class I and class III groups was not statistically significant (p > 0.05). The 5-year overall survival rate was 93% and 91%, respectively (p > 0.05). There were no significant differences in terms of recurrence rate or overall survival among patients with stage Ia2-Ib1 cervical cancer < 2 cm who underwent class I or radical (class III) hysterectomy. Morbidity was proportional to the extent of radicality. Conclusions These data confirm the need for reducing surgical radicality in the treatment of patients with early cervical cancer, by tailoring the extent of resection according to the extent of disease.

Abstract
Cervical cancer is the fourth most common malignancy in women worldwide, and resistance to chemotherapy drugs is the biggest obstacle in the treatment of cervical cancers. In the present study, the molecular mechanisms underlying cisplatin resistance in human cervical cancer cells were investigated. When human cervical cancer cells were treated with 10 µg/ml of cisplatin for 24 and 48 h, high mobility group box 1 (HMGB1) protein expression levels significantly increased in a time‑dependent manner. Comparisons between cisplatin‑sensitive HeLa cells and cisplatin‑resistant HeLa/DDP cells revealed higher levels of HMGB1 in HeLa/DDP cells than in HeLa cells. Additionally, the half maximal inhibitory concentration (IC50) value for cisplatin in HeLa/DDP cells was 5.3‑fold that in HeLa cells. Analysis of the distribution of cellular components revealed that HMGB1 translocation from the nucleus to cytoplasm contributed to cisplatin resistance. This was further confirmed by demonstration that ethyl pyruvate treatment suppressed the cytoplasmic translocation of HMGB1, resulting in inhibition of HeLa cell proliferation. Furthermore, endogenous HMGB1 was inhibited with HMGB1‑specific short hairpin (sh)RNA, and MTT assay results showed that interference with HMGB1 expression reduced cell viability and potentially reversed cisplatin resistance in HeLa cells. Transfection with HMGB1 shRNA was demonstrated to induce cell apoptosis in HeLa cells, as detected by FACS analysis. In addition, administration of recombinant HMGB1 protein in HeLa cells promoted cell autophagy, mediated by the phosphorylation of extracellular signal‑regulated kinase 1/2. Thus, cytoplasmic HMGB1 translocation and HMGB1‑induced cell autophagy are proposed to contribute to cisplatin resistance by inhibiting apoptosis of cervical cancer cells. HMGB1 could, therefore, represent a novel therapeutic target for, and a diagnostic marker of, chemotherapy resistant cervical cancers.

Abstract
The standard treatment for early cervical cancer of the uterus (CC) is radical hysterectomy with resection of the parametrium and pelvic lymphadenectomy. At least 40% of patients develop early-stage CC during child-bearing age, therefore preserving the uterus to maintain fertility has been an important consideration. Several surgical procedures including conization and vaginal or abdominal radical trachelectomy have been reported. These procedures are safe for removing lymph node negative CC tumors with <2 cm diameter. Recently, less radical surgical procedures that maintain fertility, such as conization, simple trachelectomy, minimally invasive surgery and neoadjuvant chemotherapy, have been indicated for tumors greater than 2 cm in diameter. In this review, we discuss the currently accepted surgical approaches for treating CC while maintaining fertility.

Abstract
BACKGROUND Organized cervical cancer screening services are presently lacking in Nigeria contributing to late presentation and diagnosis of invasive cervical cancer cases (ICCs) at advanced stages in most gynecologic units in Nigeria. We evaluated outcomes of ICCs diagnosed at Jos University Teaching Hospital (JUTH) to better understand factors associated with cervical cancer survival in similar resource limited settings. METHODS We performed a retrospective cohort study with a prospective follow up data to estimate time from diagnosis to mortality among women diagnosed with ICCs at JUTH. Women who were diagnosed with ICCs between January 2011 and May 2013 were followed up after initial evaluation at JUTH and subsequent referral for specialized treatment in one of the national oncology treatment centers in Nigeria. The main outcome measured was all-cause mortality rate and overall survival (OS) after diagnosis of ICC. The follow up data were updated and observations were censored March 31, 2015. The overall death rate was estimated using the total number of death events and the cumulative follow-up time from diagnosis to death. We conducted Cox proportional hazard regression to assess factors associated with death. RESULTS A total of 65 histologically confirmed ICCs were followed up. The median age of the cohort was 50 years with a median parity of 7. The HIV prevalence in the cohort was 8.2 % and the majority (72.3 %) were diagnosed at advanced stages (AD) of ICC. Simple total abdominal hysterectomy (TAH) was performed in 38.9 % of patients who were diagnosed at early stage disease (ED). After a cumulative follow up of 526.17 months, 35 deaths occurred with an overall death rate of 79.8 per 100 women-years. We also found a significantly higher hazard of death in women with AD (HR = 3.3) and baseline anemia (HR = 3.0). In the subgroup of women with ED, the OS was significantly higher for those who had TAH compared to those who did not (26.5 versus 11.6 months respectively). CONCLUSION Advanced stage disease and baseline anemia were independently associated with higher death rate. Cervical cancer patients diagnosed at early stages by non-oncologic specialist in settings lacking the standard of care may benefit from improve survival with simple hysterectomy.
