Maintenance Therapy maintenance therapy
Therapy refers to therapy may be given for patients systemic that with
Advanced after 4 to 6 cycles first-line chemotherapy. maintenance therapy is a systemic treatment that may be given to patients with advanced NSCLC after first-line chemotherapy in the period of 4 to 6 cycles (NSCLC).
Patients are candidates for therapy if they only maintenance have

However, it is only suitable for patients who have had an immediate response to their previous treatment (i.e., remission of the tumor) or stable disease and progression of the tumor.

In NCCN, for all of the selected tumor effective or stable disease, and do not consider the standard of care for patients (e.g., for PS 3 - 4, progress is not recommended), maintenance therapy is a kind of choice; close observation (2A) is an effective treatment option (see non small cell lung cancer NCCN guide).

For continued treatment, according to the approved clinical trial design, the selected drugs (given in the initial combination of traditional chemotherapy) can continue until evidence of disease progression or unacceptable toxicity.

In the ALK rearrangement or sensitive EGFR mutation negative non squamous NSCLC patients, in the initial 4 to 6 cycles of treatment (i.e., platinum based chemotherapy and bevacizumab) outside can continue bevacizumab (1 class).

In patients with non squamous NSCLC (ALK rearrangement or sensitive EGFR mutation negative), can also be given single drug pemetrexed (Level 1) as a continuation of treatment.

A recent phase 3 randomized trial (PARAMOUNT) found that pemetrexed continued to maintain a slight improvement in PFS (4.1 versus 2.8 months) compared with placebo.

The results showed that pemetrexed maintenance therapy also improved overall survival (13.9 versus 11 months).
On the trial and FDA approval, the NCCN Panel recommends the recent
Single-agent pemetrexed continuation maintenance therapy (Category 1) (as)
In patients non-squamous NSCLC without ALK rearrangements with but or
Sensitizing EGFR mutations.
Based on recent trials and the approval of the FDA, the NCCN team recommended the use of pemetrexed alone as a non - NSCLC but not ALK - or EGFR - sensitive mutation in patients with maintenance therapy (Category 1).
Maintenance therapy cetuximab was removed from the with recently NCCN
Guidelines, because first-line regimen the of
Cetuximab/cisplatin/vinorelbine was removed (see Cetuximab in this)
Cetuximab continues to be treated as recently removed from the NCCN guidelines, as the first line of cetuximab / cisplatin / vinorelbine (Changchun) is deleted.
Maintenance therapy bevacizumab/pemetrexed is an option also using in
Patients with NSCLC but ALK rearrangements without non-squamous or
Sensitizing EGFR mutations; this a category 2A is recommendation.
The use of bevacizumab / pemetrexed treatment is also continue to maintain the non squamous NSCLC but without a ALK rearrangement or sensitive EGFR mutation patients; this is a 2 class a recommendation.
From the POINTBREAK study a very slight improvement recent showed in

Bevacizumab alone maintenance therapy; the initial regimens were (as)
Either bevacizumab/carboplatin/pemetrexed or
POINTBREAK latest research data show that compared with single bevacizumab maintenance therapy, bevacizumab / pemetrexed very slight improvement of PFS (6 to 5.6 months); the initial plan is bevacizumab / carboplatin / pemetrexed or bevacizumab / carboplatin / paclitaxel.
Is important note that pemetrexed-based arm was associated to the with
Less toxicity (eg, less neurotoxicity, less neutropenia, less hair loss)
Than the paclitaxel-based arm.
It should be noted that the pemetrexed group had less toxicity than the paclitaxel combination (e.g., less neurotoxicity, fewer neutropenia, and fewer hair loss).

The latest data from the AVAPERL study shows that compared with the single use of bevacizumab, bevacizumab / pemetrexed maintenance therapy, PFS is extended by 3.7 months (7.4 to 3.7 months); the initial plan is bevacizumab / cisplatin / pemetrexed.

In addition, a phase 3 randomized trial was conducted to evaluate the optimal supportive treatment of gemcitabine after the initial cisplatin / gemcitabine regimen.
The data showed slight in PFS no difference in but overall a difference survival.
Data showed that PFS was slightly different, but overall survival was not different.
NCCN Guidelines using gemcitabine (category 2B) as recommend
Continuation maintenance regardless of histology in therapy patients
Without ALK or sensitizing EGFR rearrangements mutations.
NCCN guidelines recommend the use of gemcitabine (class 2B) as maintenance therapy in patients without ALK rearrangement or sensitive EGFR mutations, regardless of histology.
Of continuation therapy depends several factors such maintenance on as

The use of continued treatment depends on several factors, such as whether the patient has minimal toxicity during treatment.
A drug may be appropriate for some vacation more patients.
Suspension of medication may be more appropriate for some patients.
Clinicians feel continuation maintenance therapy is that only

Some clinicians believe that continued maintenance therapy is only suitable for selected patients, since it has not been shown to improve overall survival or quality of life, although it has been shown to improve PFS.
Addition, maintenance therapy not shown to be superior has to been

In addition, maintenance therapy has not been shown to be superior to the initiation of subsequent treatment at the time of disease progression.

A phase 3 randomized trial data suggest that traditional cytotoxic drugs should not be continued for more than 4 to 6 cycles; however, many patients were allocated to treatment with a longer duration and did not accept the plan period (see the discussion in the maintenance treatment).
