Epidemiology of breast cancer in women based on diagnosis data from oncologists and senologists in Algeria

BACKGROUND

Breast cancer (BC) is a major health issue threatening women's life. No reliable epidemiological data on BC diagnosed by oncologists/senologists are available in Algeria.

METHODS

The BreCaReAl study, a non-interventional prospective cohort study, included adult women with confirmed BC in Algeria. Disease incidence, patients and disease characteristics, treatment patterns, and mortality rate were recorded up to 12 months of follow-up.

RESULTS

Overall, 1,437 patients were analysed: median age was 48 [41;57] years and 337 (23.5%) women had a family history of BC. BC incidence was 22.3 (95% CI: 21.5; 23.2) cases per 100,000 inhabitants over 8 months. Delayed diagnosis was reported in 400 (29.2%) patients. First line of treatments were mainly chemotherapy and surgery. Twenty-eight serious adverse events were reported including 10 (37.0%) events which led to death. Mortality rate reached 3.2% at 12 months CONCLUSION: A delayed diagnosis highlights the importance of implementing more effective screening strategies.

Incidence of lung cancer in males and females in Algeria: The lung cancer registry in Algeria (LuCaReAl)

BACKGROUND

Lung cancer is a major cause of death worldwide. However, few data on incidence, histologic types and mortality rates of lung cancer were available for Algeria.

METHODS

LuCaReAl is an ongoing descriptive, non-interventional, national, multicenter, prospective and longitudinal study conducted in Algeria, among oncologists and pulmonologists in public community and university hospitals. Median and interquartile ranges are displayed.

RESULTS

Between July 2016 and July 2017, 897 patients were included. Overall incidence of lung cancer was 3.4 [3.2;3.6] cases per 100,000 inhabitants; overall incidence by sex was 5.8 [5.4;6.2] for males and 1.0 [0.8;1.1] for females. Adenocarcinoma was the most common histologic type of cancer. Most tumors were diagnosed at Stage IV.

CONCLUSION

The first results from the LuCaReAl study in Algeria showed that most patients are diagnosed with lung cancer at an advanced stage. The ongoing follow-up will next provide data on the survival and mortality rates.

Results at 5 years of intra vesical gemcitabine (G) single agent as adjuvant chemotheray in superficial transitional cell carcinoma (TCC) of the bladder

e16087

Background: Systemic intravenous gemcitabine is usually used in advanced bladder carcinoma, intravesical G is a novel treatment approach for TCC. In this study we evaluate the efficacy of intravesical Gemcitabine in patients (pts) with superficial bladder carcinoma. Methods: From February 2003 to June 2004, 60 pts (57M/3F) were enrolled in the study (M/F = 57/3). The median age was 59,5 years old (24–84). Nine pts had a carcinoma in situ (Cis) and 51 had pT1 lesions. Three weeks after a total transurethral resection (TUR), patients receive intravesical instillation of 2000 mg G every week for 6 weeks, than every month for six months. They received a total of 720 instillations, Follow up was with cystoscopy and urine cytology every six months. Results: At a median follow-up time 60 months, all patients were evaluable for tumor response: 23(38, 3%) patient had a persistant complete remission after treatment, 26 patients (43,3%) had a superficial relapse of TCC, six patients (10%) had progressive disease: four with muscle invasion and two with distant metastasis. Conclusions: Intravesical therapy with gemcitabine is active and well tolerated treatment in patients with superficial TCC carcinoma of the bladder. A phase III trial comparing GEM with intravesical BCG or MMC is warranted

Intra vesical gemcitabine (G) single agent as adjuvant chemotherapy in superficial transitional cell carcinoma (TCC) of the bladder: Final results

5078

Background: Systemic intravenous G is usually used in advanced bladder carcinoma. A phase I study of intravesical G has shown safety profile in pts refractory to BCG therapy (Dalbani G et al JCO 2002; 20:3193–98). In this study we evaluate the toxicity and the efficacy of intravesical G in patients (pts) with superficial bladder carcinoma. Methods: The study population criteria were: age = 18 years old, histological diagnosis of transitional cell carcinoma (TCC) of bladder (Cis and pT1) confirmed by transurethral resection (TUR), no prior chemotherapy, a performance status (PS) < 2, good bone marrow reserve, adequate renal and liver function and informed consent. Three weeks after a total TUR, pts receive intravesical instillation of 2,000 mg G every wk for 6 wks, than every month for six months. Evaluation is performed 3–4 wks after the last instillation (CT scan and/or US pelvis, urinary cytology and cystoscopy with biopsy). Results: From February 2003 to June 2004, 60 pts (57M/3F) were enrolled in the study (M/F = 57/3). The median age was 59,5 years old (24–84). Nine pts had a carcinoma in situ (Cis) and 51 had pT1 lesions. They received a total of 720 instillations. All pts were evaluable for toxicity and response Toxicity (CTC/NCI scale) is evaluated over the 720 instillations. Non haematological toxicity was grade 1: irritate bladder reaction (4.7%), asthenia (2.9%), nausea and vomiting (1.8%) and hot flashes (2%). Grade 1 haematological toxicity: anaemia (6.8%), leucopenia (4.5%) and thrombocytopenia (0.4%). After a follow-up time of 30 to 48 months, all pts were evaluable for tumor response: 53 patient had a persistant complete remission after TUR. Five patients (8.3%) had a superficial relapse of TCC (one at six months, 2 at 9 months and 2 others at 12 months). Two patients had progressive disease at 18 months and 27 months. Conclusion: Intravesical G is an active and well tolerated treatment even after repeated instillation in pts with superficial TCC carcinoma of the bladder.
