Influence of histological subtypes on the risk of an invasive recurrence in a large series of stage I borderline ovarian tumor including 191 conservative treatments

BACKGROUND

The overall prognosis of stage I borderline ovarian tumors (BOT) is excellent but a small percentage of patients die to their disease. The prognostic factors for such a rare event are still not clearly defined. The aim of this study was to determine these factors for recurrence per se and recurrence in the form of invasive carcinoma in a large series of stage I tumors.

METHODS

A retrospective review of patients with BOT. Three inclusion criteria were defined: (i) a centralized histological review; (ii) macroscopic stage I tumors; (iii) exclusion of metastatic disease to the ovaries.

RESULTS

From 2000 to 2010, 254 patients fulfilled inclusion criteria [140 had mucinous BOT (MBOT) and 114 a serous BOT (SBOT)], and 191 had undergone conservative management. After a median follow-up of 45 months, 43 patients had developed recurrences (31 borderline and 12 invasive). The risks of recurrences were statistically increased after conservative treatment, particularly after a cystectomy, in patients with stage IB and among patients with incompletely staged tumors. In the subgroup of conservatively treated patients (representing 75% of our population), the risks of recurrences were statistically increased in patients affected by a SBOT, in patients who had undergone a cystectomy, in patients with stage IB disease and in patients with a micropapillary pattern (MPP). MBOT and the presence of a MPP were identified as prognostic factors for invasive disease.

CONCLUSIONS

In the present series of BOT with the largest number of patients treated conservatively to date, the presence of a MPP and the mucinous subtype were associated with a higher rate of progression to carcinoma after conservative management. These important results suggest that MBOT belong to a 'high-risk' group likely to develop an invasive recurrence after fertility-sparing surgery in stage I BOT.

[Retinal vasculopathy in systemic lupus erythematosus: a case of lupus vasculitis and a case of non-vasculitis venous occlusion]

CLINIC CASE

Two patients with systemic lupus erythematosus presented with vision loss, and were diagnosed with retinal vasculopathy. Patient 1 had occlusive vasculitis with macular oedema and retinal ischaemia in the right eye. Corticosteroid therapy was increased and intravenous rituximab added. Intravitreal therapy and panretinal photocoagulation were performed. Patient 2 presented with a left central retinal vein occlusion without vasculitis but was on anticoagulation therapy due to having an antiphospholipid syndrome. Both patients maintained a stable visual acuity.

DISCUSSION

Occlusive lupus retinal vasculitis has severe visual and systemic consequences (central nervous system vasculitis). It is crucial to differentiate it from standard vascular occlusion syndromes.

Prognostic factors for recurrence after conservative treatment in a series of 119 patients with stage I serous borderline tumors of the ovary

BACKGROUND

The aim of this study was to evaluate prognostic factors for recurrence after conservative treatment of a large series of 'apparent' stage I serous borderline ovarian tumors (SBOTs).

PATIENTS AND METHODS

A review of 119 patients treated conservatively between 2000 and 2009 with follow-up data. All pathological slides were reviewed by the same expert pathologist. Prognostic factors for recurrence were studied (age, histological subtypes and surgical procedure).

RESULTS

Conservative surgical procedures were: unilateral cystectomy (n = 43, 36%); unilateral adnexectomy (UA; n = 50, 42%); bilateral cystectomies (n = 11, 9%) and UA + contralateral cystectomy (n = 15, 13%). Stromal microinvasion and/or a micropapillary pattern was present in 21 (18%) and 13 (11%) patients, respectively. With a median follow-up of 45 months, 38 (32%) patients relapsed (10 also had peritoneal disease in the form of noninvasive implants at the first recurrence). In 2 of these 38 patients, progression-to-invasive disease occurred at the second and third relapse (one patient died to the recurrence). Three prognostic factors for recurrence were identified in the univariate analysis: a young age (< or >30 years old), the type of conservative treatment (adnexectomy versus cystectomy) and tumor bilaterality. In the multivariate analysis, only age remained statistically significant.

CONCLUSION

In this series (the largest reported, to date, on recurrences after the conservative management of stage I SBOT), the risk of relapse was not related to tumor histological subtypes (micropapillary and stromal microinvasion) nor to the use of complete staging surgery. Invasive recurrences were very rare in stage I SBOT, but did occur. A young age, tumor bilaterality and the use of a cystectomy were identified as risk factors for recurrence, suggesting that management of fertility preservation (particularly in very young patients) should be associated with a meticulously conducted follow-up.

[Natural history of an optic disc macroaneurysm]

CASE REPORT

A 75-year old man with reduced vision in his left eye (0.05) presented with hypertensive retinopathy, retinal haemorrhages and cotton wool spots in the papillomacular bundle, as well as macular oedema. Fluorescein angiography showed a saccular hyperfluorescent lesion corresponding to arterial macroaneurysm on the optic disc, with the optical coherence tomography demonstrating macular oedema. At 2 months follow-up, vision had improved to 0.7 with spontaneous closure of the macroaneurysm and resolution of the macular oedema.

DISCUSSION

Arterial macroaneurysms on the optic disc are unusual and are difficult to diagnose clinically. There is no safe and effective treatment, and our case, as the few single cases reported, showed that they can spontaneously close and enable visual function to recover.

Paediatric and adolescent alveolar soft part sarcoma: A joint series from European cooperative groups

BACKGROUND

Alveolar soft part sarcomas (ASPS) are generally chemo- and radio-resistant mesenchymal tumours, with no standardized treatment guidelines. We describe the clinical behaviour of paediatric ASPS and compare these features to previously reported adult series.

PATIENTS AND METHODS

The clinical data of 51 children and adolescents with ASPS, prospectively enrolled in or treated according to seven European Paediatric trials were analysed.

RESULTS

Median age was 13 years [range: 2-21]. Primary sites included mostly limbs (63%). IRS post-surgical staging was: IRS-I (complete resection) 35%, II (microscopic residual disease) 20%, III (gross residual disease) 18% and IV (metastases) 27%. Only 3 of the 18 evaluable patients (17%) obtained a response to conventional chemotherapy. After a median follow-up of 126 months (range: 9-240), 14/18 patients with IRS-I tumour, 10/10 IRS-II, 7/9 IRS-III and 2/14 IRS-IV were alive in remission. Sunitinib treatment achieved two very good partial responses in four patients. Ten-year overall survival (OS) and event free survival (EFS) was 78.0 ± 7% and 62.8 ± 7% respectively. Stage IV, size >5 cm and T2 tumours had a poorer outcome, but only IRS staging was an independent prognostic factor.

CONCLUSIONS

ASPS is a very rare tumour frequently arising in adolescents and in the extremities, and chemo resistant. Local surgical control is critical. ASPS is a poorly chemo sensitive tumour. For IRS-III/IV tumours, delayed radical local therapies including surgery are essential. Metastatic patients had a poor prognosis but targeted therapies showed promising results.

Major abdominal surgery for cancer: does epidural analgesia have a long-term effect on recurrence-free and overall survival?

BACKGROUND

Retrospective studies have suggested that regional analgesia combined with general anaesthesia could decrease cancer recurrence. The purpose of this study was to assess the influence of regional analgesia on recurrence-free (RFS) and overall survival in patients undergoing major intra-abdominal surgery for cancer.

METHOD

Patients previously included in a prospective randomized study comparing two postoperative techniques of analgesia were retrospectively studied. The EP group received general anaesthesia with bupivacaine thoracic epidural analgesia and the SC group received general anaesthesia with fentanyl followed by continuous subcutaneous morphine.

RESULTS

One hundred and thirty-two patients were analyzed (63 and 69 in SC and EP group, respectively) with a 17-year-median follow-up. After 5 years, RFS was 43% [95% CI: 32%-55%] in EP group and 24% [95% CI: 15%-36%] in SC group, but the difference did not reach statistical significance for RFS nor for overall survival (P=0.10 and 0.16 respectively). Using multivariable analysis over the whole follow-up period, the type of analgesia was not a statistically significant predictive factor for RFS (EP/SC, HR=1.3 [95% CI: 0.8-2.0%]). The anaesthesia effect changed moderately over the follow-up and HR for overall survival (EP/SC) reached statistical significance after 5, 6 and 8 years.

CONCLUSION

Despite a trend in favour of the epidural, this retrospective review of patients included in a previous randomized study failed to demonstrate a statistically significant association between the perioperative analgesia and RFS after abdominal surgery for cancer. The duration of follow-up may have an impact on the analgesia effect on survival.

A randomized clinical trial of adjuvant chemotherapy with doxorubicin, ifosfamide, and cisplatin followed by radiotherapy versus radiotherapy alone in patients with localized uterine sarcomas (SARCGYN study). A study of the French Sarcoma Group

BACKGROUND

There is no proven benefit of adjuvant treatment of uterine sarcoma (US). SARCGYN phase III study compared adjuvant polychemotherapy followed by pelvic radiotherapy (RT) (arm A) versus RT alone (arm B) conducted to detect an increase ≥ 20% of 3-year PFS.

METHODS

Patients with FIGO stage ≤ III US, physiological age ≤ 65 years; chemotherapy: four cycles of doxorubicin 50 mg/m&sup2; d1, ifosfamide 3 g/m&sup2;/day d1-2, cisplatin 75 mg/m&sup2; d3, (API) + G-CSF q 3 weeks. Study was stopped because of lack of recruitment.

RESULTS

Eighty-one patients were included: 39 in arm A and 42 in arm B; 52 stage I, 16 stage II, 13 stage III; 53 leiomyosarcomas, 9 undifferenciated sarcomas, 19 carcinosarcomas. Gr 3-4 toxicity during API (/37 patients): thrombopenia (76%), febrile neutropenia (22%) with two toxic deaths; renal gr 3 (1 patient). After a median follow-up of 4.3 years, 41/81 patients recurred, 15 in arm A, 26 in arm B. The 3 years DFS is 55% in arm A, 41% in arm B (P = 0.048). The 3-year overall survival (OS) is 81% in arm A and 69% in arm B (P = 0.41).

CONCLUSION

API adjuvant CT statistically increases the 3 year-DFS of patients with US.

Plasminogen activator inhibitor-1 (PAI-1) expression in relation to hypoxia and oncoproteins in clinical cervical tumors

PURPOSE

Explore the role of plasminogen activator inhibitor-1 (PAI-1) in cervical cancer and its relationship to hypoxia and the expression of p53, Ku70/80, and cyclin D1.

MATERIAL AND METHODS

The expression of PAI-1, cyclin D1, and p53, together with tumor oxygenation, were determined in 43 consecutive patients suffering from localized cervical carcinoma. Oncoprotein expression was determined by immunohistochemistry. Tumor oxygenation was measured using a polarographic probe system, "pO2 histography."

RESULTS

PAI expression was considered negative in 32.6% and overexpressed in 18.6% of cases. Cyclin D1 showed a median expression of 5.0 (range 0-70). We observed a positive association between PAI expression and altered p53 (p = 0.049) and cyclin D1 (p = 0.020). An inverse association was detected between PAI and Ku70/80 expression (p = 0.042). Cyclin D1 staining increased according to tumor volume (r = 0.314, p = 0.009). We did not observe a significant association between PAI and hypoxia or other clinicopathological parameters.

CONCLUSION

The present results show that PAI-1 overexpression is associated with nonhomologous end-joining DNA repair down-regulation (low Ku70/80 expression) and with increased p53 and cyclin D1 expression, and they suggest that PAI-1 plays a role in the tumor behavior in cervical carcinoma.

[Central nervous system demyelinating disease-associated uveitis]

OBJECTIVE

To describe the epidemiology, clinical features and visual prognosis in uveitis associated with demyelinating disease (DD) of the CNS.

METHODS

A clinical, retrospective, and descriptive study was performed. Data regarding age at presentation, gender, time from onset was recorded, as well as, type of uveitis, complications, treatment and initial and final visual acuity (BCVA) on all patients with DD-associated uveitis diagnosed in our Unit between January 2009 and June 2011.

RESULTS

Five women and 4 men were finally included (1.3% of 697 with uveitis). There was associated multiple sclerosis in 78% of cases. Mean age at presentation was 36.6 years for uveitis and 40 years for DD. The uveitis preceded the DD in 3 cases (33%). Typically, uveitis was bilateral (89%), chronic (89%), intermediate (89%), and associated with previous inflammation (29%), with synechiae (65%), and granulomatous (44%). The most frequent complications were cataract (71%) and macular oedema (53%). Besides local treatment, uveitis was managed with systemic steroids (78%), immunosuppressants (44%), and surgery (41% of eyes). After a mean follow up of 5 years, 47% of the eyes had a worse BCVA, among which, 12% lost ≥ 3 Snellen lines. The only patient treated with interferon (IFN), remained stable without treatment for the last 7 years.

CONCLUSIONS

DD-associated uveitis typically affected young adult women with intermediate-anterior uveitis of chronic, bilateral and synechiae type. Complications are common and there is a risk of visual loss, despite treatment. IFN therapy may be an effective alternative to be investigated.

[Delayed diagnosis of ophthalmic artery obstruction due to atrial myxoma]

CASE REPORT

A 56 year old woman with atrial myxoma presented with a visual acuity of no light perception after acute ophthalmic artery obstruction (OAO) associated with stroke. She developed late retinal pigmentary changes due choroidal infarction, typical of the OAO.

DISCUSSION

Simultaneous obstruction of the retinal and choroidal circulation was observed in the OAO. Atrial myxoma should be suspected in patients who suffer from OAO associated with stroke. Systemic studies should be performed to find the origin of OAO.

Comparison of different wound closure techniques in translabyrinthine acoustic neuroma surgery

In a series of 277 patients with translabyrinthine acoustic neuroma, three techniques of wound closure were used to prevent cerebrospinal fluid (CSF) leakage. In the first group, we used a piece of fascia to cover the dural defect and then placed several pieces of fat on the fascia. The incidence of CSF leak was 28.2%; 7.7% required reoperation. In the second group, in addition to the fasia-fat complex, we made a large musculoperiosteal flap to compress the fat. The incidence of CSF leak and revision were not reduced, however. In recent cases, we placed several pieces of fat directly into the operative cavity without fascia graft; then it was covered with a musculoperiosteal flap. With this technique, CSF leak was significantly reduced to 7.4%, and reoperation was rare (3.7%). The direct application of fat into the translabyrinthine operation cavity appears to be effective to prevent CSF leaks.

Brain Abscesses of Ear, Nose, and Throat Origin: Comparison between Otogenic and Sinogenic Etiologies

This retrospective study analyzed 29 cerebral abscesses of ear, nose, and throat (ENT) origin. The mean follow-up of patients was 37 months. ENT etiologies included 45% otitis media (n = 13), 48% sinusitis (n = 14), and 7% ethmoidal sinus tumors (n = 2). Thirty-eight percent (n = 5) of otogenic abscesses occurred within 15 days after a mastoidectomy. Sinogenic abscesses were never due to surgery but were associated in 31% of cases (n = 5) with anterior skull base defects. The main locations of otogenic abscesses were the temporal lobe (54%; n = 7) and the cerebellum (23%; n = 3), whereas sinogenic abscesses were located in the frontal lobe in 75% of cases (n = 12). Because of this location, sinogenic abscesses were less symptomatic than otogenic ones and had greater size and encapsulation at the time of diagnosis. Thus, they required longer antibiotic treatment (p = 0.05) and more numerous surgical drainages (p = 0.02). Bacteriologic abscesses samples were positive in 90% of cases. Bacteria found in brain abscesses were different from the ones found in ENT samples in 62% of cases. Thus, the results of ENT bacteriologic samples were not helpful for choosing adequate antibiotic agents in case of negative brain abscess samples. Although mortality was not significantly higher in otogenic abscesses (31%; n = 4) than in sinogenic ones (6%; n = 1, p = 0.08), otogenic abscesses appeared more threatening. Indeed, they represented 80% (n = 4) of lethal cases and encompassed more clinical or radiological prognosis pejorative factors than sinogenic ones (p = 0.006). In conclusion, higher danger of otogenic abscesses mainly resulted both from their temporal or cerebellous locations and from the bacteria that were more frequently resistant to antibiotics.

Loggerhead sea turtle bycatch data in artisanal fisheries within a marine protected area: fishermen surveys versus scientific observations

Loggerhead sea turtles can be incidentally captured by artisanal gears but information about the impact of this fishing is inconsistent and scarce. Recent studies have observed that the bycatch, or incidental catch rate, in fishermen surveys is irregular. The aim of this study was to compare direct data (onboard observers) concerning the incidental catch of loggerhead sea turtles by the artisanal vessels versus data from fishermen surveys. The study area was the Cabo de Gata-Níjar marine protected area, situated in the western Mediterranean (southeast of the Iberian peninsula). We observed two loggerhead turtles that were incidentally caught in a total of 165 fishing operations. According to fishermen surveys, a total of nine loggerheads were incidentally caught in 861 fishing operations. The differences between the loggerhead sea turtle bycatch reported by fishermen surveys and scientific observations versus random distribution (x2 = 0.3146, P = 0.575, df = 1) were not significant. We conclude that the surveys are useful but that findings should be interpreted with caution.
