Confiabilidad interevaluador de la medición de la excursión diafragmática y fracción de engrosamiento diafragmático mediante ultrasonografía en voluntarios sanos / Inter-rater reliability of the measurement of diaphragmatic excursion and fraction of diaphragmatic thickening by ultrasonography in healthy volunteers

Antecedentes y objetivo: Determinar la confiabilidad interevaluador en la medición ultrasonográfica (US) de la excursión diafragmática (ED) y la fracción de engrosamiento diafragmático (FED) realizada por profesionales de salud no médicos en voluntarios sanos. Participantes y métodos: Estudio observacional prospectivo en un hospital de tercer nivel en Cali, Colombia. Se realizaron mediciones a 30 voluntarios sanos escogidos mediante muestreo a conveniencia, sin antecedentes de enfermedades pulmonares, con edades entre los 18-60 años. Previamente se realizó una prueba piloto con 8 voluntarios sanos. Las mediciones US de ED y FED se basaron en protocolos publicados anteriormente. Cada evaluador observaba independientemente varios ciclos de respiración tranquila normal durante 3minutos para establecer una línea de base. Para evaluar la confiabilidad interevaluador en las mediciones de ED y FED se utilizó el índice de correlación intraclase (ICC), con intervalos de confianza del 95% y un p<0,05. Resultados: Se identificó concordancia sustancial en la medición de la ED en las ventanas esplénica y hepática debido a que el ICC fue mayor a 0,6 (p<0,05). La medición de la FED en la ventana hepática mostró concordancia leve tanto en el modo 2D como en el modo M (p>0,05). En la ventana esplénica la medición de la FED en el modo 2D se identificó concordancia regular y para el modo M se encontró una concordancia leve (p>0,05). Conclusiones: La US diafragmática constituye un método reproducible con aceptable confiabilidad interevaluador para la medición del grosor inspiratorio/espiratorio y con confiabilidad pobre para la medición de FED.(AU)

Background and objective: To determine the inter-rater reliability in the ultrasonographic (US) measurement of the diaphragmatic excursion (DE) and the diaphragm thickness fraction (DTF) performed by non-medical health professionals in healthy people. Participants and methods: Prospective observational study in a third level hospital in Cali, Colombia. Measurements were made to 30 healthy volunteers chosen by convenience sampling, without a history of lung diseases, with ages between 18-60 years. A pilot test was previously carried out with 8 healthy volunteers. US measurements of DE, and DTF were based on previously published protocols. Each assessor independently observed several cycles of normal quiet breathing for 3minutes to establish a baseline. The Intraclass Correlation Index (ICC) was used to evaluate the inter-rater reliability in the measurements of DE and DTF, with 95% confidence intervals and a P<.05. Results: Substantial agreement was identified in the measurement of DE in the splenic and hepatic windows because the ICC was greater than 0.6 (P<.05). The measurement of the DTF in the hepatic window showed slight agreement in both 2D and M modes (P>.05). In the splenic window, the measurement of the DTF in the 2D mode was found to be moderate agreement and for the M mode a slight agreement was found (P>.05).Conclusions: The diaphragmatic US constitutes a reproducible method with acceptable inter-rater reliability for the measurement of inspiratory/expiratory thickness, and with little reliability for the measurement of DTF.(AU)

Overall survival results of AGO-OVAR16: A phase 3 study of maintenance pazopanib versus placebo in women who have not progressed after first-line chemotherapy for advanced ovarian cancer.

OBJECTIVE: The AGO-OVAR16 study was designed to test the efficacy, safety, and tolerability of pazopanib maintenance after first-line chemotherapy in patients with newly diagnosed advanced ovarian cancer (AOC). METHODS: Nine hundred and forty patients with histologically confirmed AOC, International Federation of Gynecology and Obstetrics (FIGO) stage II-IV, were randomized in a 1:1 ratio to receive either 800 mg pazopanib once daily or placebo for up to 24 months, unless there was disease progression, toxicity, withdrawal of consent, or death. The primary endpoint (investigator-assessed progression-free survival [PFS]) was met and previously reported. The results of final analyses of overall survival (OS) are reported here. RESULTS: A third OS interim analysis showed futility and led to study closure and a final OS analysis after last patient last visit. At the time of the final OS analysis, 494 (89.7% of the planned 551) events had occurred. No difference was observed in OS between pazopanib and placebo. The hazard ratio (HR) was 0.960 (95% confidence interval [CI]: 0.805-1.145), and the median OS from randomization was 59.1 months in pazopanib and 64.0 months in placebo arms. For the East Asian patients, similar to the first three interim OS analyses, a numerical negative trend was observed favoring placebo (HR, 1.332; 95% CI: 0.863-2.054). Exploratory analyses showed a trend for a longer time to first subsequent anti-cancer therapy or death with pazopanib over placebo (HR, 0.829; 95% CI: 0.713-0.965), with a median estimate of 19.0 and 14.5 months, respectively. No new safety signals were observed. CONCLUSION: Although pazopanib prolonged PFS, this was not associated with improvement in median OS. CLINICAL TRIAL INFORMATION: ClinicalTrials.gov: NCT00866697.

Biomarkers predict enhanced clinical outcomes with afatinib versus methotrexate in patients with second-line recurrent and/or metastatic head and neck cancer.

BACKGROUND: In the phase III LUX-Head & Neck 1 (LUX-H&N1) trial, second-line afatinib significantly improved progression-free survival (PFS) versus methotrexate in patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). Here, we evaluated association of prespecified biomarkers with efficacy outcomes in LUX-H&N1. PATIENTS AND METHODS: Randomized patients with R/M HNSCC and progression following ≥2 cycles of platinum therapy received afatinib (40 mg/day) or methotrexate (40 mg/m2/week). Tumor/serum samples were collected at study entry for patients who volunteered for inclusion in biomarker analyses. Tumor biomarkers, including p16 (prespecified subgroup; all tumor subsites), EGFR, HER2, HER3, c-MET and PTEN, were assessed using tissue microarray cores and slides; serum protein was evaluated using the VeriStrat® test. Biomarkers were correlated with efficacy outcomes. RESULTS: Of 483 randomized patients, 326 (67%) were included in the biomarker analyses; baseline characteristics were consistent with the overall study population. Median PFS favored afatinib over methotrexate in patients with p16-negative [2.7 versus 1.6 months; HR 0.70 (95% CI 0.50-0.97)], EGFR-amplified [2.8 versus 1.5 months; HR 0.53 (0.33-0.85)], HER3-low [2.8 versus 1.8 months; HR 0.57 (0.37-0.88)], and PTEN-high [1.6 versus 1.4 months; HR 0.55 (0.29-1.05)] tumors. Afatinib also improved PFS in combined subsets of patients with p16-negative and EGFR-amplified tumors [2.7 versus 1.5 months; HR 0.47 (0.28-0.80)], and patients with p16-negative tumors who were EGFR therapy-naïve [4.0 versus 2.4 months; HR 0.55 (0.31-0.98)]. PFS was improved in afatinib-treated patients who were VeriStrat 'Good' versus 'Poor' [2.7 versus 1.5 months; HR 0.71 (0.49-0.94)], but no treatment interaction was observed. Afatinib improved tumor response versus methotrexate in all subsets analyzed except for those with p16-positive disease (n = 35). CONCLUSIONS: Subgroups of HNSCC patients who may achieve increased benefit from afatinib were identified based on prespecified tumor biomarkers (p16-negative, EGFR-amplified, HER3-low, PTEN-high). Future studies are warranted to validate these findings. CLINICAL TRIAL REGISTRATION: NCT01345682.

Phase II randomized study of PM01183 versus topotecan in patients with platinum-resistant/refractory advanced ovarian cancer.

BACKGROUND: PM01183 is a new compound that blocks active transcription, produces DNA breaks and apoptosis, and affects the inflammatory microenvironment. PM01183 showed strong antitumor activity in preclinical models of cisplatin-resistant epithelial ovarian cancer. PATIENTS AND METHODS: Patients with platinum-resistant/refractory ovarian cancer were included in a two-stage, controlled, randomized (in a second stage), multicenter, phase II study. Primary endpoint was overall response rate (ORR) by RECIST and/or GCIG criteria. The exploratory first stage (n = 22) confirmed the activity of PM01183 as a single agent at 7.0 mg flat dose every 3 weeks (q3wk). The second stage (n = 59) was randomized and controlled with topotecan on days 1-5 q3wk or weekly (every 4 weeks, q4wk). RESULTS: ORR was 23% (95% CI, 13%-37%) for 52 PM01183-treated patients. Median duration of response was 4.6 months (95% CI, 2.5-6.9 months), and 23% (95% CI, 0%-51%) of responses lasted 6 months or more. Ten of the 12 confirmed responses were reported for 33 patients with platinum-resistant disease [ORR = 30% (95% CI, 16%-49%)]; for the 29 patients treated with topotecan in the second stage, no responses were found. Median PFS for all PM01183-treated patients was 4.0 months (95% CI, 2.7-5.6 months), and 5.0 months (95% CI, 2.7-6.9 months) for patients with platinum-resistant disease. Grade 3/4 neutropenia in 85% of patients; febrile neutropenia in 21% and fatigue (grade 3 in 35%) were the principal safety findings for PM01183. CONCLUSION: PM01183 is an active drug in platinum-resistant/refractory ovarian cancer and warrants further development. The highest activity was observed in platinum-resistant disease. Its safety profile indicates the dose should be adjusted to body surface area (mg/m2). TRIAL CODE: EudraCT 2011-002172-16.

Afatinib versus methotrexate in older patients with second-line recurrent and/or metastatic head and neck squamous cell carcinoma: subgroup analysis of the LUX-Head & Neck 1 trial.

BACKGROUND: In the phase III LUX-Head & Neck 1 (LHN1) trial, afatinib significantly improved progression-free survival (PFS) versus methotrexate in recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients progressing on/after platinum-based therapy. This report evaluates afatinib efficacy and safety in prespecified subgroups of patients aged ≥65 and <65 years. PATIENTS AND METHODS: Patients were randomized (2:1) to 40 mg/day oral afatinib or 40 mg/m(2)/week intravenous methotrexate. PFS was the primary end point; overall survival (OS) was the key secondary end point. Other end points included: objective response rate (ORR), patient-reported outcomes, tumor shrinkage, and safety. Disease control rate (DCR) was also assessed. RESULTS: Of 483 randomized patients, 27% (83 afatinib; 45 methotrexate) were aged ≥65 years (older) and 73% (239 afatinib; 116 methotrexate) <65 years (younger) at study entry. Similar PFS benefit with afatinib versus methotrexate was observed in older {median 2.8 versus 2.3 months, hazard ratio (HR) = 0.68 [95% confidence interval (CI) 0.45-1.03], P = 0.061} and younger patients [2.6 versus 1.6 months, HR = 0.79 (0.62-1.01), P = 0.052]. In older and younger patients, the median OS with afatinib versus methotrexate was 7.3 versus 6.4 months [HR = 0.84 (0.54-1.31)] and 6.7 versus 6.2 months [HR = 0.98 (0.76-1.28)]. ORRs with afatinib versus methotrexate were 10.8% versus 6.7% and 10.0% versus 5.2%; DCRs were 53.0% versus 37.8% and 47.7% versus 38.8% in older and younger patients, respectively. In both subgroups, the most frequent treatment-related adverse events were rash/acne (73%-77%) and diarrhea (70%-80%) with afatinib, and stomatitis (43%) and fatigue (31%-34%) with methotrexate. Fewer treatment-related discontinuations were observed with afatinib (each subgroup 7% versus 16%). A trend toward improved time to deterioration of global health status, pain, and swallowing with afatinib was observed in both subgroups. CONCLUSIONS: Advancing age (≥65 years) did not adversely affect clinical outcomes or safety with afatinib versus methotrexate in second-line R/M HNSCC patients.

SEOM guideline in ovarian cancer 2014.

Ovarian cancer is the leading cause of death due to gynecological cancer and the 5th cause of death for cancer in women in Europe. Optimal management of patients with ovarian cancer needs the participation of a well-trained multidisciplinary team. In the last few years, we have observed a significant improvement in the knowledge of the molecular biology of the different histotypes of ovarian cancer that will probably change our standard of care in the forthcoming years. In this Guideline, we summarize the most current evidence for the medical management of ovarian cancer.

A randomized, phase II study of afatinib versus cetuximab in metastatic or recurrent squamous cell carcinoma of the head and neck.

BACKGROUND: Afatinib is an oral, irreversible ErbB family blocker that has shown activity in epidermal growth factor receptor (EGFR)-mutated lung cancer. We hypothesized that the agent would have greater antitumor activity compared with cetuximab in recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) patients, whose disease has progressed after platinum-containing therapy. PATIENTS AND METHODS: An open-label, randomized, phase II trial was conducted in 43 centers; 124 patients were randomized (1 : 1) to either afatinib (50 mg/day) or cetuximab (250 mg/m(2)/week) until disease progression or intolerable adverse events (AEs) (stage I), with optional crossover (stage II). The primary end point was tumor shrinkage before crossover assessed by investigator (IR) and independent central review (ICR). RESULTS: A total of 121 patients were treated (61 afatinib, 60 cetuximab) and 68 crossed over to stage II (32 and 36 respectively). In stage I, mean tumor shrinkage by IR/ICR was 10.4%/16.6% with afatinib and 5.4%/10.1% with cetuximab (P = 0.46/0.30). Objective response rate was 16.1%/8.1% with afatinib and 6.5%/9.7% with cetuximab (IR/ICR). Comparable disease control rates were observed with afatinib (50%) and cetuximab (56.5%) by IR; similar results were seen by ICR. Most common grade ≥3 drug-related AEs (DRAEs) were rash/acne (18% versus 8.3%), diarrhea (14.8% versus 0%), and stomatitis/mucositis (11.5% versus 0%) with afatinib and cetuximab, respectively. Patients with DRAEs leading to treatment discontinuation were 23% with afatinib and 5% with cetuximab. In stage II, disease control rate (IR/ICR) was 38.9%/33.3% with afatinib and 18.8%/18.8% with cetuximab. CONCLUSION: Afatinib showed antitumor activity comparable to cetuximab in R/M HNSCC in this exploratory phase II trial, although more patients on afatinib discontinued treatment due to AEs. Sequential EGFR/ErbB treatment with afatinib and cetuximab provided sustained clinical benefit in patients after crossover, suggesting a lack of cross-resistance.

GEICO (Spanish Group for Investigation on Ovarian Cancer) treatment guidelines in ovarian cancer 2012

In 2006, under the auspices of The Spanish Research Group for Ovarian Cancer (Spanish initials GEICO), the first "Treatment Guidelines in Ovarian Cancer" were developed and then published in Clinical and Translational Oncology by Poveda Velasco et al. (Clin Transl Oncol 9(5):308-316, 2007). Almost 6 years have elapsed and over this time, we have seen some important developments in the treatment of ovarian cancer. Significant changes were also introduced after the GCIG-sponsored 4th Consensus Conference on Ovarian Cancer by Stuart et al. (Int J Gynecol Cancer 21:750-755, 2011). So we decided to update the treatment guidelines in ovarian cancer and, with this objective, a group of investigators of the GEICO group met in February 2012. This study summarizes the presentations, discussions and evidence that were reviewed during the meeting and during further discussions of the manuscript (AU)

SEOM guidelines for endometrial cancer

Endometrial cancer (EC) is the most common gynaecological tumour in developing countries. Most patients with EC are diagnosed at an early stage with a low risk of relapse and overall survival at 5 years greater than 85%. Nevertheless, there is a subgroup of patients with a very poor prognosis due to the pathological features and molecular characteristics. Until now there has been no consensus regarding adjuvant treatment in EC patients, with many open questions: In which patients is it indicated? Which is the best approach: chemotherapy, radiotherapy or both? What is the right timing? Relevant clinical trials are in progress in order to answer these questions. Unfortunately, the survival of patients with metastatic or recurrent EC is quite short due to the poor responses to standard first-line chemotherapy and the lack of second lines of treatment (AU)

SEOM guidelines for cervical cancer

Cervical cancer (CC) is the second most common cancer worldwide, with a well known origin, infection by high-risk human papilloma virus. Although screening programmes have led to a relevant reduction in the incidence and mortality due to CC in developed countries, it is still an important cause of mortality in young women in undeveloped countries. Clinical stage is the most relevant prognostic factor in CC and the standard of care is still based on it. In early stages, the primary treatment is surgery or radiotherapy, whereas concomitant chemo-radiotherapy is the conventional approach in locally advanced stage. In the setting of recurrent or metastatic CC the treatment is largely palliative, so it is important to develop new therapeutic strategies (AU)

Effects of lapatinib monotherapy: results of a randomised phase II study in therapy-naive patients with locally advanced squamous cell carcinoma of the head and neck.

BACKGROUND: Lapatinib is a dual inhibitor of epidermal growth factor receptor (EGFR) and human EGFR-2 (HER-2) tyrosine kinases. This study investigated the pharmacodynamic and clinical effects of lapatinib in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN). METHODS: In total, 107 therapy-naive patients with locally advanced SCCHN were randomised (2 : 1) to receive lapatinib or placebo for 2-6 weeks before chemoradiation therapy (CRT). Endpoints included apoptosis and proliferation rates, clinical response, and toxicity. RESULTS: Versus placebo, lapatinib monotherapy did not significantly increase apoptosis detected by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick-end labelling or caspase-3 assays. A statistically significant decrease in proliferation using Ki67 assay was observed (P=0.030). In a subset of 40 patients that received 4 weeks of lapatinib or placebo, objective response rate (ORR) was 17% (n=4/24) vs 0% (n=0/16). In the lapatinib single-agent responders, all had EGFR overexpression, 50% had EGFR amplification, and 50% had HER2 expression by immunohistochemistry (including one patient with HER2 amplification). However, these patients showed variable modulation of apoptosis, proliferation, and phosphorylated EGFR on drug treatment. Following CRT, there was a statistically non-significant difference in ORR between lapatinib (70%) and placebo (53%). There was no clear correlation between changes in apoptosis or proliferation and response to chemoradiation. Mucosal inflammation, asthenia, odynophagia, and dysphagia were the most commonly reported adverse events with lapatinib. CONCLUSION: Short-term lapatinib monotherapy did not demonstrate apoptotic changes, but provided evidence of clinical activity in locally advanced SCCHN, and warrants further investigation in this disease.

Feasibility of a modified outpatient regimen of intravenous/intraperitoneal chemotherapy in optimally debulked stage III ovarian cancer patients: a GEICO study.

OBJECTIVES: The objective of the study was to assess the feasibility, toxicity, and reasons for early discontinuation of a modified outpatient intraperitoneal/intravenous (IP/IV) chemotherapy regimen for the treatment of patients with optimally debulked stage III ovarian cancer. METHODS: Between February 2006 and November 2008, 51 consecutive patients from Institutions of the Spanish Ovarian Cancer Group (GEICO) were treated with a modified outpatient IP chemotherapy regimen. Patients received IV paclitaxel 175 mg/m over 3 hours on day 1, followed by IP cisplatin 100 mg/m (or 75 mg/m according to the principal investigator's criteria) on day 2. On day 8, patients received IP paclitaxel 60 mg/m. To homogenize the IP administration and supportive measures, a GEICO guideline for IP chemotherapy was established. Patients were treated with the intention to receive 6 courses of chemotherapy every 21 days. RESULTS: The median age of the patients was 49 years (range, 36-75 years), and most of them had papillary serous ovarian cancer (78%), International Federation of Gynecology and Obstetrics stage IIIC (76%). Thirty-nine patients completed 4 or more IP cycles, and 28 (61%) completed all 6 IP cycles. Twenty-two patients discontinued the IP/IV treatment, mainly because of chemotherapy toxicity (10 patients) and catheter-related complications (5 patients). The most prevalent grade 3/4 toxicities were neutropenia (14 patients; 30%) and gastrointestinal events (12 patients; 26%). CONCLUSIONS: The GEICO outpatient modified regimen resulted in a lesser toxicity and a greater rate of treatment completion than previously reported. The accurate selection of patients and the administration following well-defined guidelines can increase the feasibility of IP chemotherapy administration.

Phase II randomized study of trabectedin given as two different every 3 weeks dose schedules (1.5 mg/m2 24 h or 1.3 mg/m2 3 h) to patients with relapsed, platinum-sensitive, advanced ovarian cancer.

BACKGROUND: This randomized, open-label, phase II clinical trial evaluated the optimal regimen of trabectedin administered every 3 weeks in patients with platinum-sensitive, relapsed, advanced ovarian cancer (AOC). PATIENTS AND METHODS: Patients previously treated with less than two or two previous chemotherapy lines were randomized to receive trabectedin 1.5 mg/m(2) 24 h (arm A, n = 54) or 1.3 mg/m(2) 3 h (arm B, n = 53). Objective response rate (ORR) per RECIST was the primary efficacy end point. Toxic effects were graded according to the National Cancer Institute-Common Toxicity Criteria v. 2.0. RESULTS: ORR was 38.9% [95% confidence interval (CI) 25.9% to 53.1%; arm A] and 35.8% (95% CI 23.1% to 50.2%; arm B) (intention-to-treat primary analysis). Median time to progression was 6.2 months (95% CI 5.3-8.6 months; arm A) and 6.8 months (95% CI 4.6-7.4 months; arm B). Frequent severe adverse events were nausea/vomiting (24%, arm A; 15%, arm B) and fatigue (15%, arm A; 10%, arm B). Common severe laboratory abnormalities were transient, noncumulative neutropenia (55%, arm A; 37%, arm B) and transaminase increases (alanine aminotransferase, 55%, arm A; 59%, arm B). CONCLUSIONS: Both every-3-weeks trabectedin regimes, 1.5 mg/m(2) 24 h and 1.3 mg/m(2) 3 h, were active and reasonably well tolerated in AOC platinum-sensitive patients. Trabectedin every-3-weeks has promising activity and deserves to be further evaluated in relapsed AOC.

Clinical surrogate markers of survival in advanced non-small cell lung cancer (NSCLC) patients treated with second-third line erlotinib.

BACKGROUND: Inhibition of the EGFR pathway is a useful strategy in the treatment of patients with advanced NSCLC. The aim of this study is to assess predictive clinical parameters of efficacy. METHODS AND PATIENTS: Sixty-two patients with advanced NSCLC were treated with erlotinib as second-third line (150 mg/day). Baseline patient characteristics were: performance status (PS) 1: 92%; median age, 58 years; males, 73%; adenocarcinoma, 45%; current/former smokers, 83%. During erlotinib treatment, 35% of patients had no rash, 32.3% had grade 1 rash, 26% had grade 2 rash and 6.5% patients developed grade 3 rash. RESULTS: For patients with grades 2-3 rash vs. those with grades 0-1 rash, time to tumor progression (TTP) and overall survival (OS) were 92 vs. 41 days (p=0.0381) and 244 vs. 131 days (p=0.011), respectively. For patients with non-smoking history and current/former smokers, TTP and OS were 136 vs. 42 days (p=0.0015) and 324 vs. 133 days (p=0.0242), respectively. In addition, rash grade and smoking history were found to have a highly significant impact on TTP and OS, according to the Cox model. CONCLUSIONS: Grade > or =2 rash and non-smoking history are associated with improved TTP and OS in advanced NSCLC patients treated with erlotinib.

Risk of recurrence during follow-up for optimally treated advanced epithelial ovarian cancer (EOC) with a low-level increase of serum CA-125 levels.

BACKGROUND: Our group evaluated the risk of recurrence for optimally treated advanced epithelial ovarian cancer (adEOC) in patients with a low-level rising serum CA-125 concentration within the normal range (0-35 kU/l). In addition, we tested the new proposed early CA-125 signal of progressive disease (EPD) criterion in the same study population. PATIENTS AND METHODS: Patients treated from 1998 to 2006 for adEOC were identified at our institution. Inclusion criteria were as follows: CA-125 at time of diagnosis (>35 kU/l); International Federation of Gynecology and Obstetrics stages III-IV treated with optimal primary treatment; and complete response (CR) to primary treatment with normalization of CA-125. RESULTS: Median progression-free survival and overall survival for the recurrence group (n = 60) were 17.7 and 38.2 months, respectively. The median follow-up time from CR to last contact was 40.2 months for patients in the nonrecurrence group (n = 36). An absolute increase in serum CA-125 levels of >or=5 kU/l compared with baseline CA-125 nadir values was significantly predictive of recurrence (odds ratio for recurrence = 402.98, P < 0.0001). The progression date was predated by the EPD criterion in 77% of patients with known progressive disease (median, 58 days early) with a sensitivity of 90%, a positive predictive value of 96.4%, and a false-positive rate of 5.6%. CONCLUSIONS: Among patients with optimally treated adEOC in complete remission, a low-level increase in serum CA-125 concentration within the normal range is a strong independent predictive factor for disease recurrence. In this patient population, future prospective randomized trials should consider the evaluation of the EPD criterion.

Nadir CA-125 concentration in the normal range as an independent prognostic factor for optimally treated advanced epithelial ovarian cancer.

BACKGROUND: The amount of residual disease after surgery is considered the most important factor influencing the survival of patients with advanced epithelial ovarian cancer (adEOC). In optimally treated patients with adEOC, there are no well-established prognostic factors [excluding International Federation of Gynecology and Obstetrics (FIGO) stage]. The aim of this retrospective study is to analyze the prognostic value of the CA-125 nadir after the completion of an optimal primary treatment. PATIENTS AND METHODS: Patients treated for adEOC were identified from January 1998 to December 2006. INCLUSION CRITERIA: elevated CA-125 at time of diagnosis (>35 kU/l); FIGO stage III-IV treated with optimal primary treatment (residual tumor <1 cm and carboplatin/taxane-based combination chemotherapy); and complete response to optimal primary treatment with normalization of CA-125. RESULTS: Patients, n = 96: 44 group A (< or =10 kU/l); 52 group B (11-35 kU/l). Median progression-free survival (PFS) was 42 and 20 months for groups A and B, respectively (P = 0.0087). Median overall survival (OS) was 84 and 43 months for groups A and B, respectively (P < 0.0001). The Cox model showed a highly significant impact on PFS and OS in relation to CA-125 nadir levels. CONCLUSIONS: The CA-125 nadir value is a strong independent prognostic factor for optimally treated adEOC after achieving a complete response.

Update in the management of ovarian and cervical carcinoma.

Ovarian and cervical cancers are significant health problems. This article provides an update in selected management topics. Paclitaxel and platinum derivatives are the first-line treatment for patients with advanced disease. In selected patients, intraperitoneal chemotherapy has been associated with improved survival but the broad applicability of this strategy is limited by issues of toxicity and feasibility. Management of patients with recurrent disease is based on a number of factors and includes surgery in selected cases, platinum-based chemotherapy for patients with platinum-sensitive disease and other agents such as topotecan and pegylated liposomal formulation of doxorubicin for patients with platinum-resistant disease. In cervical cancer, the most significant issue/event is the demonstration of superior survival with topotecan and cisplatin compared to cisplatin alone. Finally, new agents such as epidermal growth factor receptor inhibitors and antiangiogenic agents are being currently tested in these settings.
