Can you be fully cured of ovarian cancer?
· The PARP inhibitor Zejula (niraparib) has been approved for use as maintenance therapy in patients with recurrent ovarian cancer who are in complete or partial response to platinum-based chemotherapy. Zejula unlike other PARP inhibitors is active both in patients with and those without BRCA mutations.
What is the life expectancy after ovarian cancer?
Treatment of recurrent OC ‘Platinum-sensitive’ recurrence Platinum-based therapy continues to be the principal regimen used to treat tumours that recur at least 6 months after prior therapy [ Markman et al. 1991 ]. Carboplatin monotherapy is very convenient to administer, well tolerated and produces relatively high response rates (RRs).
What is the latest treatment for ovarian cancer?
In patients not pretreated with bevacizumab in first line, the carboplatin/gemcitabine/bevacizumab combination, followed by maintenance is a viable alternative in platinum-sensitive patients (PFI> 6 months). The integration of surgery, with a 'personalized' approach by the use of antiangiogenic agent and of PARP inhibitors is affecting …
What to expect from Stage III ovarian cancer?
Treatment for recurrent ovarian cancer can include options such as: surgery chemotherapy (drugs that aim to kill cancer cells) targeted therapies (drugs that attack specific types of cancer cells with less harm to normal cells) hormonal therapy (drugs that block the amount of hormones in the body to slow down cancer growth)
How many times can you have chemotherapy for recurrent ovarian cancer?
Continued Standard Chemotherapy: The standard course of initial chemotherapy is approximately 6 cycles, or about 4 months of treatment. If, after 6 cycles, there is a small amount of persistent cancer, some doctors feel further chemotherapy treatment for 10 or 12 cycles may continue to cause shrinkage of the cancer.
What is the prognosis for recurrent ovarian cancer?
Ovarian cancer recurs in most patients, with a 5-year survival rate less than 30%. Quality of life is an increasingly important issue in patients with cancer, but there are limited data in women with recurrent ovarian cancer in this regard.
Can recurrent ovarian cancer go into remission?
About 80% of women who are diagnosed with ovarian cancer will go into remission after their initial treatment, but around 60% will then have a recurrence. The goal of maintenance therapy is to delay a cancer recurrence or to reduce the risk of it recurring at all.
What chemo is used for recurrent ovarian cancer?
Two of these agents, pegylated liposomal doxorubicin (PLD) and topotecan, are FDA approved for the treatment of recurrent ovarian cancer. PLD is currently the most frequently utilized of all the options in this setting, yet drug shortages in 2011 and beyond have changed prescribing.
Is recurrent ovarian cancer terminal?
Recurrent ovarian cancer is a lethal disease, and few patients can be cured. Although most patients receive standardized surgery and chemotherapy, the status of recurrent disease is heterogeneous. The site of recurrence and the survival intervals after recurrence are also widely distributed.
Can you beat ovarian cancer twice?
Some ovarian cancers are very sensitive to platinum chemotherapy. So you might be able to have this treatment multiple times over many years. But most women will develop a resistance to platinum drugs over time.
Can you be cured of recurrent ovarian cancer?
Outlook. Your medical team can use chemotherapy and other treatments to slow cancer growth and control symptoms, but recurrent ovarian cancer is rarely curable.
What are symptoms of recurrent ovarian cancer?
Symptoms of recurrence are abdominal pain, bloating, nausea, or vomiting and changes in bowel or bladder habits. If you have these symptoms, please talk to your gynecologic oncology team quickly. If ovarian cancer returns, you will likely have chemotherapy, either one type alone or several kinds in combination.
What causes ovarian cancer recurrence?
Ovarian cancer recurrence takes place when residual cancer cells persist during and after a patient's initial course of treatment, or when cancer cells return following preliminary therapy and a period of remission.
What is the standard of care for recurrent ovarian cancer?
Studies have demonstrated that platinum- and taxane-containing chemotherapy improves the survival of women with ovarian cancer over other types of regimens. As a result, the combination of a platinum-type drug (usually carboplatin) and a taxane (usually paclitaxel) is the standard chemotherapy regimen.
Is there immunotherapy for ovarian cancer?
Immunotherapy is class of treatments that take advantage of a person's own immune system to help kill cancer cells. There are currently three FDA-approved immunotherapy options for ovarian cancer.
Can you go into remission with stage 4 ovarian cancer?
Most patients with Stage III and Stage IV ovarian cancer will be able to go into remission.
How to detect ovarian cancer?
Persistent ovarian cancer is detected either by an elevated CA-125 blood level, abnormal x-rays and CT scans, or with a biopsy performed during second-look laparotomy.
What is Avastin therapy?
Avastin is a targeted therapy that blocks a protein known as VEGF. VEGF plays a key role in the development of new blood vessels. By blocking VEGF, Avastin deprives the cancer of nutrients and oxygen and inhibits its growth. The addition of Avastin® to standard chemotherapy significantly improves progression-free survival and objective response rate among women with platinum-resistant recurrent ovarian cancer. (1)
What is persistent cancer?
Persistent cancer refers to residual cancer growths or cells that persist during and following initial treatment. Patients who have achieved complete remission following initial therapy and who subsequently experience a return of cancer cells after treatment are said to have relapsed or recurrent cancer.
What is ovarian cancer?
Ovarian cancer (OC) is the fifth most common cause of cancer death in women. Although significant progress has been made in the treatment of OC, the majority of patients experience disease recurrence and receive second-line and sometimes several lines of treatment. Here we review the options available for the treatment of recurrent disease ...
How long does ovarian cancer last?
The progression-free survival (PFS) has remained fairly constant at about 18 months.
What is icon4/ovar 2.2?
ICON4/OVAR 2.2 was the first large-scale randomized phase III trial to compare the addition of a second drug to platinum-based therapy. Paclitaxel added to platinum, most commonly carboplatin, extended both the PFS and OS of patients with recurrent OC [Parmar et al.2003]. Median PFS was increased significantly from 10 to 13 months. The benefit in OS was smaller, corresponding to an absolute difference of 7% at 2 years (57% compared with 50%). This regimen has frequently been used as a reference treatment for newer comparative trials. However, the inclusion of paclitaxel increases toxicity, notably, hair loss and more peripheral neuropathy, and these side effects are of greater concern when the length of benefit gained by combination chemotherapy is relatively short. This led to a trial in which carboplatin and paclitaxel were compared with carboplatin and pegylated liposomal doxorubicin (PLD). The trial, CALYPSO, was designed as a noninferiority study. The toxicity profile was shown to be better than with carboplatin and paclitaxel and there was an increase in the PFS [Pujade-Lauraine et al.2010]. However, on further follow up there was no improvement in OS [Wagner et al.2012]. Interestingly, the incidence of carboplatin allergy, a relatively common occurrence when retreating patients with relapsed disease, was lower when the drug was combined with PLD compared with paclitaxel [Bafaloukos et al.2010; Wagner et al.2012].
How often is CA125 tested?
Whilst some variation in clinical practice continues, most patients still undergo routine testing of CA125 at intervals of approximately 3 months for the first 2 years. CT imaging is triggered by an elevation in CA125 or clinical symptoms. The routine use of more complex imaging with positron emission tomography computed tomography (PET-CT) to pick up disease earlier is unlikely to be cost effective. The principal role of PET-CT is to identify occult disease that may contraindicate surgery.
Does surgery help with OC?
The role of surgery in the management of relapsed OC is uncertain. It is usually performed in women with a recurrence in only a few anatomical sites, usually after a long treatment-free interval. However, the extent to which this procedure adds to PFS or overall survival (OS) is unclear. The data demonstrating a benefit are derived from retrospective studies [Harter et al.2009; Zang et al.2011]. The German AGO (Arbeitsgemeinschaft Gynaekologische Onkologie) group defined a group of patients who benefit most based on the presence of at least two of the three following criteria: complete resection at first surgery, good performance status and absence of ascites [Harter et al.2009]. The benefit of surgery can only be determined by a randomized trial and two ongoing randomized trials led by AGO and the Gynecologic Oncology Group may provide an answer to the question of whether surgery improves the outcome of OC in first recurrence.
Does chemotherapy extend the survival of ovarian cancer patients?
The sequential use of chemotherapy regimens and the incorporation of molecularly targeted treatments, either alone or in combination with chemotherapy, have over the last decade significantly extended the median survival of patients with ovarian cancer.
Is platinum free relapse reversible?
In vitroand clinical data have shown that platinum resistance is not necessarily a stable phenomenon; it is inducible and perhaps reversible [Kavanagh et al.1995; Horowitz et al.2004]. A subgroup analysis of the OVA 301 trial which compared PLD with or without trabectedin, a DNA minor groove binding drug, suggested there was a benefit in delaying the PFI by using a nonplatinum combination therapy. Patients with ‘partially platinum-sensitive’ relapse had an improved PFS and a 41% reduction in the risk of death compared with those treated with PLD alone [Monk et al.2010]. It is hypothesized that treatment with nonplatinum drugs to extend the PFI can render cells more sensitive to platinum drugs and this may partially explain the survival benefit observed in the partially platinum-sensitive population following reintroduction of subsequent platinum therapy [Kaye et al.2011]. This needs confirmation in a prospective trial. Two trials that compare the use of nonplatinum therapy with platinum-based treatment followed by crossover at next progression are in progress. One of these uses the combination of trabectedin and PLD (INOVATYON trial) [ClinicalTrials.gov identifier: {"type":"clinical-trial","attrs":{"text":"NCT01379989","term_id":"NCT01379989"}}NCT01379989], and the other compares PLD with carboplatin and paclitaxel, crossing over to the other regimen on progression (MITO-8) [ClinicalTrials.gov identifier: {"type":"clinical-trial","attrs":{"text":"NCT00657878","term_id":"NCT00657878"}}NCT00657878].

What is maintenance therapy for ovarian cancer?
There are two main types of maintenance therapy used for ovarian cancer. One of these is Avastin (bevacizumab). This drug stops tumors from using blood vessels to feed themselves and grow. Another type of maintenance therapy is a category of drugs called poly (ADP-ribose) polymerase, or PARP, inhibitors. PARP inhibitors include Lynparza (olaparib), Zejula (niraparib), and Rubraca (rucaparib). PARP inhibitors make it harder for cancer cells to repair DNA damage, leaving them more vulnerable. These drugs are especially effective in treating cancers with mutations in the BRCA gene.
