Prevalence and indicators of cure of Italian women with vulvar squamous cell carcinoma: A population-based study

Five-year net survival and conditional survival from vulvar squamous cell carcinoma (VSCC) patients in Italy have shown no progress during the past three decades. This study aims to estimate the complete prevalence and multiple indicators of cure. Observed prevalence was estimated using 31 Italian cancer registries covering 47 % of Italian women. A subset of 22 cancer registries was used to estimate model-based long-term survival and indicators of cure, i.e., complete prevalence, cure fraction (CF), time to cure (TTC), proportion of 'already cured' patients, and cure prevalence. In 2018, VSCC patients alive in Italy (complete prevalence) were 6620 or 22 per 100,000 women. The cure fraction (the proportion of newly diagnosed patients who will not die of VSCC) did not change between 2000 and 2010 both for all patients (32 %) and in each age group. The time to cure (5-year conditional net survival >95 %) was 11 years for patients aged ≥44 years, but excess mortality remained for >15 years in the other age groups. This led to a negligible (5 %) proportion of 'already cured' patients (living longer than time to cure). The proportion of patients alive <2 years (21 %) was the same as that of patients surviving ≥15 years. The cure prevalence (patients who will not die of VSCC) was 64 %. A considerable proportion of patients will not be cured even among those who survived ≥5 years. There is an urgent need to reshape the current vulvar care model in Italy.

Indicators of cure for women living after uterine and ovarian cancers: a population-based study

Abstract This study aims to estimate long-term survival, cancer prevalence, and several cure indicators for Italian women with gynecological cancers. Thirty-one cancer registries, representing 47% of the Italian female population, were included. Mixture cure models were used to estimate net survival, cure fraction, time to cure (when 5-year conditional net survival becomes &amp;gt; 95%), cure prevalence (women who will not die of cancer), and already cured (living longer than time to cure). In 2018, 0.4% (121 704) of Italian women were alive after diagnosis of corpus uteri cancer, 0.2% (52 551) after cervical cancer, and 0.2% (52 153) after ovarian cancer. More than 90% of patients with uterine cancers and 83% with ovarian cancer will not die from their neoplasm (cure prevalence). Women with gynecological cancers have a residual excess risk of death &amp;lt;5% at 5 years after diagnosis. The cure fraction was 69% for corpus uteri, 32% for ovarian, and 58% for cervical cancer patients. Time to cure was ≤10 years for women with gynecological cancers aged &amp;lt;55 years; 74% of patients with cervical cancer, 63% with corpus uteri cancer, and 55% with ovarian cancer were already cured. These results can contribute to improving follow-up programs for women with gynecological cancers and supporting efforts against discrimination of already cured ones.
